A Hard Lesson in Bike Geometry

Last weekend I learned a lesson in bicycle geometry.

At my UBI frame-building class, we learned the basics of why almost all bikes have fairly similar geometry (or "virtual geometry" in the case of compact-style frames), at least within their class -- road, MTB, cyclocross, BMX, hybrid, etc., etc.  As a frame builder, you can experiment with changes ... but will usually quickly find out why your novel geometry just does not work for its intended purpose.

So for the Yamabushi, I followed the traditional geometry pretty carefully, starting with frame measurements from my last two road bikes, and adjusting for a cyclocross build -- with slightly longer chain stays, 425mm instead of 405-410mms, and allowing for a longer fork.

I built up the bike with a Ritchey cyclocross fork, which has a vertical measurement of 391mm from the fork crown to the axle, and an offset (rake) of 45mm.  This is a bit short for a cyclocross fork (they range 390-410mm), but noticeably longer than a standard road fork of 365-375mm.  The extra length allows for fatter tires and mud clearance, of course.  Anyway, the Ritchey works perfectly, and the result is a bike that is comfortable to ride and handles well.  The Yamabushi is not as nimble as, say, my 2007 Cervelo R3-SL was, but it is stable, and it responds well, going just where I point it, when I point it.

Last weekend I put on the bike a new fork with disk brake mount, attached the new Avid BB-7 disk brake and my recently built wheel with a disk rotor.  I  added "The Plug II" (USB charger off the dynamo hub), and was excited to find that everything seemed to work.

I went out for a spin.

The brake is great -- much more control, and better stopping power, than the V-brakes I have been using.  The new front wheel with 50mm carbon clincher rim feels very fast.  The Schwalbe Ultremo 700x28 tires roll fast and are very comfortable with the extra air volume -- perfect for a Brevet that will go over good quality roads.

But the bike seemed to steer oddly.  It felt as if I was steering a boat, with a very little rudder pushing against a strong current.  At first, I thought something was wrong with the headset or the fork installation -- too tight, or too loose?  Or maybe the disk brake cable was gumming up the steering?  After eliminating these choices, I decided to compare the new fork with the one I had removed.
Left side -- a fork too long. 
Sure enough, the new fork has a crown-axle measurement of 410mm, 19mm longer than the Ritchey, and at least 10mm greater rake than the Ritchey.  The longer fork pushes the front end of the bike up, resulting in a reduced head tube angle.  This, plus the added rake/offset, push out the front axle noticeably ahead of the steering axis.

The feeling was odd.  Very odd.  Size does matter.  And shape.

I will try again with another fork as soon as it arrives.


UPDATE:  I got the new fork, which has the same rake as the Ritchey (45mm) and is in between the two in length 400mm).  The handling is no longer boat-like.  The wheel seems very fast and the disk brake very nice.  The steering is more Cadillac than Porsche, but that seems very stable, and fine for most uses.  Tomorrow I will ride it to work and if all is well, give it a real test the coming weekend.

UPDATE2:  As an experiment, I switched back to 700x35 cyclocross tires (Continental "Speed" version -- for hard packed dirt and pavement, roll reasonably well) from the 700x28 slicks I had tried before.  This increases the effective diameter of the wheel and this the "trail" of the wheel's contact point a bit more, and the handling shifts from Cadillac in the direction of Porsche.  It is a bit odd that fatter tires with more tread result in nimbler handling ... but that is so.

Still, the cyclocross tires definitely roll slower than normal road tires.  I ordered some 700x30 Grand Bois touring tires that randonneurs seem to rave about (distributed in the U.S. by the rider who completed Cascade 1200 with the fastest time this year ...  so they may be fat, but they're not slow!)

UPDATE3:  I noticed that the FSA headset I have had on the Yamabushi (used, removed from frame I rode 2001-2006) was noticeably gummed up.  Some lubricant helped a bit, but still the steering seemed a bit resistant.  Maybe this was at least a contributing factor to the "boat" feeling.  In any event, I put on a new Cane Creek headset I ordered last month.  Yes, I have a headset press and a removal tool,which have now pretty much paid for themselves by getting their first use!  With the new headset and the Grand Bois tires, the front end us very responsive, slightly toward the "twitchy" end of the spectrum.  But when I put an Ortlieb handlebar bag off the front, the handling seems really perfect -- as close as possible to "neutral".  I will ride this combination on a cold 400km Brevet tomorrow.

UPDATE4 (February 3):  I have now used the disk brake and 400mm fork on the 400km Brevet, and since for almost 3 weeks of commuting and riding in the city.  I have come to the conclusion that the bike handling issues I had were at least significantly the result of the gummed up, very old FSA headset.  The bike handling has been just fine with the new headset, with any of 3 sets of tires, with or without a handlebar bag.  If I get some extra time, I might even try swapping back in the 410mm/more rake fork just to see if it is more rideable now with the new headset ... but no time right now.

Off Season Rest

With short, cold days, some wet weather, plenty of (domestic Japanese) business travel and work, I have not gotten in many long rides since Jerome and I did an intense Brevet in early October.  This has been my "off season", from late October until early January ... with riding to start the new year depending on schedule and weather.

I have at least been working on my bikes and reading a Google-hosted U.S. randonneur discussion board, which has focused over the last few days on a Mayo Clinic study announced in June and published in "Heart" magazine that suggests too much intense exercise over too many months and years, can damage the heart and lead to increased incidence of early death.

A Thanksgiving week Wall Street Journal article sensationalized this, with a headline suggesting runners had "one foot in the grave".  (The article is available here ... behind the WSJ paywall.)

One key is to be sure not to exercise at too high an intensity for too long a period.  Brevets require very extended effort, but the intensity level is quite low -- and the key to riding a longer Brevet is to know how to continue to make the greatest forward progress with the least effort.  Managing intensity levels is very important for proper training.  Short bursts of intensity -- intervals, hill climbs -- are crucial.  And books such as Younger Next Year (co-written by the doctor younger brother of a former colleague of mine) suggest a big mistake older people make is to avoid intensity altogether.  But training at too intense a level for too long a period will certainly grind down an athlete and it seems reasonable that it could damage the heart muscle.

Another key is to be sure to allow adequate recovery time after any kind of extreme event.  As much as a month is required for full recovery after a marathon, a longer triathlon, or a weeklong cycling event such as Transalp.  A Boulder Colorado newspaper article provides nice balanced report.

So does riding a longer Brevet or randonee damage the heart?  I do not know.  It probably depends on how one rides the event.  If the Brevet can be completed at moderate intensity, without extreme sleep deprivation, and with adequate recovery, then I doubt it is harmful.  And riding these or other multi-day events is an acquired skill.  The first time I did Tokyo-Itoigawa, I could barely get out up off the floor the next morning.  Now it seems like just a regular hard single day.  After trying PBP in 2011, I felt as if I had put myself through a brutal punishment.  But after subsequent long events, I get through without nearly the degree of suffering, and I recover much more quickly.

If exercise involves extreme intensity and punishment ... and is followed too soon by other similar events, rinse and repeat, then yes, it may not be good for one's health.  Is that really a surprise?

Long Term Road Test -- Japanese Punctureless Tire Tube

There was an era, back in the 1960s and early 70s, when American cars had a very short lifespan.  The manufacturers did not mind -- in fact, they wanted it this way, since customers would want to buy a new car every 2 or 3 years.  Planned obsolescence.

The only problem with this strategy was that American cars got a reputation for being very poorly made.   Japanese cars won a place in the U.S. market because they lasted a long time.  A Toyota, Nissan or Honda would run trouble free for a decade or more.  The Honda Civic or Toyota Corolla with over 100,000 miles and 10 years was a standard "graduate student" or even "junior faculty" car at many U.S. universities.  U.S. manufacturers eventually got the message, and their quality improved, eventually closing in on the Japanese manufacturers.  Today, the average car on the road in the U.S.A. is something like 11 years old -- the oldest ever.  Even as population increases, the U.S. does not need as many new cars each year.  Little wonder that GM and Chrysler needed bail-outs back in 2009.

The same thing is happening around the world with light bulbs.  We used to have incandescent bulbs that lasted maybe 1000 hours on average and consumed 60 watts.  Now we have LED bulbs that last 50 times as long, and consume 10% the wattage for the same brightness.  Yes, LEDs are much more expensive, but it is nice to put one in a light socket and know that it should last as long as I am in my house.  Without any light bulb changes, it is only a matter of time before the end of light bulb jokes.

Could the tire tube be about to undergo a similar transformation?

After my speech in May 2011 to the bicycle usage promotion study group run by Shigeki Kobayashi, a Chiba-based inventor named Suzuki-san came up and started to tell me about his latest award-winning invention -- a tire tube that is nearly puncture proof (well, he markets it as "very difficult to puncture" -- not wanting to overstate his claim).

I was pleasantly surprised to receive, a week or two later, a package in the mail with a gift of two of his patented, award winning Isshin Tasuke tire tubes, plus some explanatory material.  

The tubes felt heavy -- they weigh around 250 grams, as opposed to 90 for a regular Vittoria 18-25x700 road bike tube.  I was not sure I would want to use them.  And I am not sure you want to hear about them either -- tubes are not the most exciting piece of equipment on a bicycle.

The 一新助け(Isshin Tasuke) Tube weighs 247 grams
A Vittoria standard road tube weighs 91 grams.
But the next time I changed to a new a tire on my Bianchi (commuting bike) rear wheel, in June 2011, I tried out one of Suzuki-san's tubes.

I recently changed a threadbare rear tire on the Bianchi for the second time since then.  I put the same Isshin Tasuke tube right back in this third tire.  No flats for almost 18 months of mostly urban riding.  

True, I have not used the Bianchi as much this year as in 2010 and 2011 -- less daily commuting, and more urban riding on the Yamabushi this fall.  But still, no tube punctures in what must be thousands of kilometers, through the entire life of 2 normal road bike tires (both Vittoria -- supple, light, good grip, and high TPI, but nothing extraordinary in terms of puncture protection).

I have never understood the explanatory material that Suzuki-san provided.  Either a lack of Japanese or of technical knowledge.  The tubes have some kind of little loose granular items inside.  You can hear these rolling on the inside as you spin up at the start of a ride ... but they are silent once you have been riding for a minute, and do not seem to cause a noticeable change in rolling resistance.  Yes, the tubes are heavy, not recommended for a hill climb race, but the road feel is acceptable, and for normal riding the convenience certainly more than compensates for the additional weight.

After 18 months, the loose granular substance seems to be forming into lumps on one side of the tube, but it is certainly still useable.  I plan to ride it until it finally punctures.

I just put the second tube from Suzuki-san on the rear wheel of the Yamabushi.  If all goes well, I will use this rear wheel, with the new road disk brake/carbon clincher front wheel, on a 400km brevet in mid January around the Seto Nai Kai.  It will be a bit different than the usual road bike setup, but it is not a hilly course, and it will be worth it if I can avoid changing even one or two flats while out riding in the cold this winter.

Is this a better approach than the Air Protect Max goop that Hutchinson makes, or the Stan's No Tubes sealant, for insertion into a tire?  I do not know.   The sealants add around 100 grams of weight to the tire, if properly used -- not much different than the Isshin Tasuke approach.  I tried the Hutchinson goop a few times on my road tubeless tires 4 or 5 years back, ... and it seemed to end up oozing out under the tire bead and hardening on the back of the seat tube, where needless to say it did not serve its purpose.  Others like the sealants -- David and Juliane used them in the 2011 Transalp in their tubulars, and made it through the week without a flat.

You can order the Isshin Tasuke tubes (Japanese language only) online at 

or via fax at 04-7132-2415.

They are not cheap -- at 2850 yen for a road bike version.  Then again, if they last as long as 5 or even 10 regular tubes and save you from all those flat tire incidents, they are not expensive either.  The same concept as the LED light.

Looking forward to the next 20 years

I had the honor of riding the Cascade 1200 and Rocky Mountain 1200 this summer with Ken Bonner, one of the most decorated endurance/Brevet riders around.  According to the BC Randonneurs homepage, he has recorded over 178,000 kilometers of lifetime Brevet distance.  (The BC Randonneurs have established a separate award that is reserved for riders who record long distances "other than Ken", to make sure others get some kind of recognition and he does not monopolize things.)

More accurately, I should say that I had the honor of riding the first ninety minutes or so of the Cascade 1200 with or near Ken... then did not see him again, as I slowed to a more sustainable pace, bonked on the first day's late afternoon long climb, stopped each night, etc., while Ken just "rode through", then returned home for some grandparent duties.

Likewise I did not see him on the Rocky Mountain 1200, where Ken's group started 6 hours later than mine, and finished 18 hours+ sooner.  I think he probably passed at Jasper while I was sleeping.

So I was interested to learn that Ken just celebrated his 70th birthday by doing 70 hours of riding ... another 1600 kms.

Most important, he looks happy!

Cyclepedia to PDX

Last year I got the book "Cyclepedia", which is essentially a catalogue of the most impressive collection of bicycles in the world, the Embacher Collection in Vienna.  It covers an incredible range of history, bikes from all over the world, all eras, all genres -- road, mountain, track, touring, tandem, folding, cargo, urban, and other designs.  The common themes among the 100 bikes are innovation and stylish design, indeed, iconic design.
The book is available on Amazon.com, and the content (plus 360 degree photos) is now also an ipad app.

Now, I am told that the collection will be on show from June 8 to September 8, 2013 at the Portland Art Museum, Portland, Oregon.  Another great reason to be in Portland at some point during the summer months.

Stelvio Dreams

Some great photography of cycling on the Stelvio in early winter.  See


And for a recent 1 minute video of cycling the Stelvio in winter (hat tip to www.mamil.cc ).

The electronica music in the video starts the heart pumping, makes me want to get on the bike and find a climb!

Some great photography of cycling on the Stelvio in early winter, by the same photographer ... same trip, presumably.  See


Then there is cycling the Stelvio via fixed gear ... how many tires were consumed in this descent?

Almost as good as this photo of Juliane and David J. climbing the Stelvio end of June 2009.

I won't get back there this summer.  ...   Maybe 2014?

25 November 2012


Stephen was in town again this weekend from Hong Kong, and Jerome joined him Saturday evening at his place in Ikusabata, west of Oume.  The weather was spectacular -- clear and crisp, with the autumn colors near peak.
Jerome takes photos on the Nokogiri descent
I left home around 7:20AM Sunday and tried to make decent time without working too hard, getting to Stephen's a little after 9:30AM.  Jerome had gone on a major convenience store run and gathered breakfast items, which we ate on the porch in the sunlight.  It was cold even in the sun, with a breeze and perspiration on my jersey chilled after a few minutes resting.
More from the grotto/water hole on the Nokogiri South side descent
We rode up to Yoshino Kaido to Kori, then further up via Okutama Kaido to Okutama Station and, a few minutes beyond, to the left hand entrance to the climb.  It was great to finally get off the main road and away from the tourists.
At the top of Nokogiri, Stephen is ready for more. ... plenty of warm layers.
The road is in better condition than the last time I did this climb, in January 2011, 22 months ago.   And the cool weather was perfect.  I climbed without any photo stops, but also without any effort to push hard ... and still managed to shave 2 1/2 minutes off my prior best time.  Cool weather and better road conditions make a difference.  On the descent, we stopped at the small water hole just after the short tunnel ... for more photos.
Cover photo for next year's "Men of Positivo Espresso" calendar?

Warm layers ... but could use some full finger gloves.
Jerome came to the rescue and lent a pair.

This is why we ride on side roads into the mountains.

We went down the South side and together as far as Itsukaichi, where I headed for home.  140 kilometers, one big climb, and home before 3PM.

Bike Craft -- wheels 00008 and 00009

A rainy Saturday, and I was still recovering from a cold so gave up on my plan for a longer Sunday ride.  I built up two wheels, number 00008 and 00009, using the last two of my SP Dynamo hubs. One is a Velocity A23 hub, with Sapim CX Ray spokes (32 x 3 cross), and with the PV-8 hub.  It is identical to my 2012 Brevet wheel, except for the PV-8 instead of an SV-8.  I will see if I can notice any difference, in drag or output, and will keep it in reserve or find it a good home.

The other is made with a 50mm carbon clincher rim from GS Astuto, an SD-8 (disk brake version) and an Avid BB-7 road disk rotor.  Also 32x3 cross CX Ray spokes.   32 spokes is overkill with this deep a rim for a front wheel.  I will install a GS Astuto cyclocross fork with disk mount on the Yamabushi, with this wheel, and try the setup on 2013 Brevets in Japan.  The speed of a deep carbon rim, the ease of a clincher, no worries about the rim as a braking surface, and an opportunity to experiment with a quality mechanical disk brake -- supposedly allowing for more nuanced braking.  I cannot wait to try it.
Super Brevet wheel

I picked up a great Pillar spoke wrench at GS Astuto along with the rim and fork -- really helps to build wheels with speed and confidence.  Like night and day.

L'Eroica 2012

L'Eroica 2012

Juliane and I cannot remember when or why we decided to ride the L'Eroica. It was about a year ago and, I think, inspired by some of the articles I read when I bought my first vintage bike. So the first question must be, "why buy a vintage bike?" I'm afraid, the answer is far from simple. Something to do with the blend of science, craftsmanship and art that produced wonderfully responsive hand-built frames in the 50's, 60's and 70's, many from small workshops at the back of the shop. Frames, for example, built by unique characters like the irascible Major Nichols - who would throw potential customers out of his shop if he didn't like 'the cut of their jib', Claude Butler, who built some of the best frames in the country before his slide into alcoholism, and the Major Brothers, who were building frames for off-road 'rough stuff' many decades before anyone thought of a mountain bike. All of this a million miles from modern factory produced carbon and alloy frames all available on e-bay for a couple of hundred quid if you spot something that others miss.

As our bike and frame collection grew it was inevitable that we would have to go to the premier vintage bike event in the World. L'Eroica started 15 years ago with a handful of riders campaigning against the ever advancing tarmac that was gobbling up apace the 'strade bianche' - unmade gravel and dust roads so typical of the Tuscan countryside. And the roads that many of Italy's most famous riders learnt their trade on - honing bike handling skills on the unstable surfaces and building stamina on the undulating terrain.

Impetuously, flights and hotels were booked and on-line entries made for the 205 km long course before really doing too much research into what was involved. It soon was evident that we had taken on a significant challenge. The long course has close to 4000m of climbing and about 100 km on gravelled 'strade bianche'. Much of the climbing (and descending) is off road, 10%, 15% even some 20% up and down. We noticed that vintage bikes have vintage brakes!

Originally we had planned to ride two e-bay purchases - a beautiful 1952 Holdsworth Cyclone (cost 150 pounds) and a Carlton clubman from the 60's (100 pounds). The Holdsworth is a joy to ride, the Carlton isn't. The 'cyclone' was a top of the range frame - lightweight, responsive - weighing in as a built up bike at around 11kg. The Carlton seems to built of scaffolding poles and recycled u-boat parts with the frame alone close to 11kg... Luckily though, we received a very timely wedding present in the shape of the 1970's Claude Butler 'majestic' that has been hanging up in Dad's garage for years. The majestic was a touring bike rather than a lightweight racer. However touring gears and generally good condition made it a clear favourite over the Carlton.

Thursday 5th October was departure day. Bikes packed in travel boxes and carrying a couple of backpacks, we took the train to Gatwick for our flight to Pisa. After an overnight stay in Pisa we unpacked the bikes and took the train to Sienna for lunch in the famous town square before riding to our hotel close to the event HQ in Gaiole. On the train we met, Oscar from Tijuana, the first ever Mexican to ride the event. He had a beautiful Swiss, all chrome framed, bike that he had bought out of a skip for 10 pounds from a house clearance. It wasn't difficult to spot cyclists making their way to the event - down tube gear shifters are a give away! I cannot describe the event any better than this account from a fellow rider: http://www.cyclingtips.com.au/2012/10/leroica/. This is the official website and here is a bit of data:

For us the day itself was both the hardest we have had on a bike and the best. The combination of old bikes and equipment on surfaces that can be truly awful and very steep coupled with the terrain make the long course a true test of resolve and fitness. We were very pleased to finish in twelve and a half hours. The good humour and genuine friendliness of all the other riders made the whole day a joy. Compared to other big events we have ridden like the week long Transalp race, L'Eroica doesn't have a high concentration of the obsessed racers trying to grind each other into the road. L'Eroica is about the bikes and the people who appreciate them and have the heart to ride them.

We saw riders labouring on fixed wheel bikes from the 1920's, we saw French, Italian and Spanish bikes. We rode with Italians singing 'Felicita'. We rode with Englishmen singing 'ten green bottles'. At the feed stops we ate local delicacies, salami, ham, cheese, local bread and cakes. We drank local red wine poured by volunteers in period costume. At the last stop we even had sweet 'vin santo' served with cantuccini biscuits!

We talked with Bob from Bristol on his Hetchins, Tim from Birmingham on his Major Nichols, Gene from New York on his Gios Torino, and many, many others. We stopped to see if Oscar from Mexico needed a hand when we saw him stopped by the side of the road. Everyone was friendly and helpful.
Luckily you don't have to torture yourself over 200 km. Three shorter rides are also offered, so no excuses not to give it a go.

We'll be back - David Jacob

Riding the Rindo on Fat Tires

On Saturday morning, I finally took the slick tires off my steel-framed cyclocross bike (the "Yamabushi") and tried out the Continental 700x35 "speed" tread cyclocross tires.  They roll with much less resistance than the Ritchey CX tires I got last Spring, which have big knobby grips for going through mud.

On Sunday, I rode out to Lake Miyagase, climbed the closed forest road between Route 64 and Route 70, and headed home.  The ride was around 140 kms, and I think my average speed for the day was only 1~2 kph slower than on road bike tires, making this setup a reasonable trade-off for the ability to ride on gravel and hit the occasional rock without slicing a tire or hearing that awful hissing sound of air escaping.

The weather was cool, around 10 degrees celsius / 50 fahrenheit for much of the ride, and in the countryside traffic was very sparse, weekend fall foliage crowd scared off by the forecast of rain for the afternoon and gradually darkening clouds.  I made it back at 3PM, just as the first drops started.
Continental "Speed" Cyclocross tires, on A23 rims, Chris King classic hubs, and 32 spokes 3X pattern, with the drive side DT Competition and non-drive side DT Revolution.  So far, so good.
On the way back in along Onekan, I came across Gunnar and his wife, Nami, and rode with them for a few kilometers.  Gunnar is still basking in the glory of his victory last week at Hotaka.  He said it was the first time Nami has ridden Onekan ... but she seems able to take the rollers at a good clip, and will no doubt be leaving the rest of us in the dust in no time.

Rindo Entrance off of Route 64 just down the hill South of Miyagase-ko

On the rindo, no traffic, and no people until I came across 2 hikers quite close to the exit at Route 70. 

The road was relatively clear at first, but eventually I came across leaf-covered sections, which made it difficult to see the randomly strewn rocks and some huge potholes, requiring a slow pace.  I was glad to have the fat tires.

The fall foliage is out ... and would be blazing on a sunny day.

At Tsukui-ko, I took the eastern bridge for the first time in several years, instead of the west-end bridge that connects to the forest road along the North shore.  I do not even remember there being a pedestrian span--on the right-hand side.

Wiggins hit by car while training near home -- full recovery expected

Ouch.  Here is an early report.  Happens even to the best of cyclists.

Ti Travel Bike -- 10 Orders Needed

Tim Smith of GS Astuto mentioned to me on Sunday that he is looking to get at least 10 customers so he can place an order for the model of Ti frame with SandS couplers I got as a test case.  There will be a selection of sizes that should work for 95% of body types and sizes.

It is a great frame (or complete bike) and a great bargain.

If you want to travel with your Titanium bike next summer, now is the time to contact Tim.

For the review of my frame, see Ti Travel Bike and Bike in a (small) Box.

Tsuru Toge Again!

An overdue post from a ride 2 weeks ago.  Stephen C. was back in town, and Jerome visited his place in Oume, staying out there Saturday evening.  Didier and I headed out to meet them for a Sunday ride, in spectacular riding weather.

We rode fast to make the 10AM rendezvous point, at Kori between Oume and Okutama-ko.  Stephen had already headed up toward Okutama-ko, wanting a head start.  I took a quick rest and continued on toward him, while Didier and Jerome wanted a bit more time at Kori.

I waited for them at the far end of Okutama-ko, the bridge where Route 139 leaves Route 411.  There was way too much traffic on Route 411 for me to want to climb Yanagisawa Pass, again.  But Stephen was still farther up the road, already at Tabayama.  We tracked him down by mobile phone (lucky) and agreed he would come over Imagawa Pass to meet us.  We would go via Route 139/Kosuge and climb toward Imagawa Pass from the south side.

We met Stephen near the top, descended back to Kosuge ... with me getting a flat near the bottom as my rims overheated from constant braking.  Imagawa is deceptive.  It looks like a beautiful forest road -- kind of like the nicest sections of Sasago Pass.

But it is all over 10%, much of it 13-15% in grade.  I made the mistake of stopping for some photos, and needed to walk at least 50 meters up the hill to a slightly wider road area before I could remount.

We climbed from Kosuge again to the base of Matsuhime, but Didier and I decided that we would only get back to Tokyo if we instead went via Tsuru Pass, down Route 18/33 to Uenohara.  Jerome and Stephen climbed with us to the top, then headed back down to Okutama and Oume -- they would ride again the next day.

At the top, as we said farewell, I could not help noticing the power lines that blocked the view to the South.  I used to think of these as visual pollution.  Now that I am trying to develop some solar power projects, I think "6.6kV, high voltage line, appropriate for interconnection of projects up to 2MW peak output."
And when I look at the pole at the top of the pass, I think "automatic load balancer; is there any place nearby that would be a decent solar project site?"  (In this case, ... no.)
Anyway, we said our farewells and Didier and I headed for home, quickly.  It was over 180 kms for me, and about 200 for Didier, at a good pace.  I felt strong most of the way, as if I am getting some benefit from regular rides over the prior month, plus commuting more in town on bike than I was during the summer heat.
On the way from Tsuru Pass toward Uenohara.  A beautiful road!

Looking back toward Tsuru/Tawa Passes, as a nearby resident approaches.

Cycle Mode 2012 - Makuhari Messe

I have not been to Cycle Mode -- the closest thing Japan has to EuroBike or InterBike --  in a number of years ...  usually it conflicts with some great riding weather, and there is nothing new under the sun, or very little.  And I have heard grumbling from exhibitors -- it takes a lot of time, effort and money, and in Japan the show does not seem to translate into sales for most companies.

But after missing it for a few years, and getting more interested in "the industry", I thought I should attend.

This year Trek, Giant and Specialized were noticeably absent, though Pinarello, Colnago, Chesini, De Rosa and other Italian brands were there.  Cervelo had a small display.  Shimano was there, of course, and Campy Japan.  I did not see SRAM.  Presumably whether someone participates has a lot to do with the specific importer/distributor relationships and whether companies feel they can avoid the show without it damaging their business and prospects.  It is a "command performance" for major Japanese brands, and for some others trying to expand here.

There were a few highlights for me.

1.  Chesini.  Of course, stopping by the Chesini booth, to see Hiroshi Koyama, and also meet Mr. Chesini and his daughter (in law?) visiting from Verona.  Hiroshi has been actively promoting the Chesini brand in Japan via C Speed.  It is a small brand, but has a long history, back to 1925, and its bikes have some world championship victories to their credit.  Chesini is to Verona what Sambi is to Ravenna?  But more so.

2.  Gokiso Hubs.  Are these the best hubs in existence?  Tim Smith (GS Astuto) and David Marx (RGT Enterprises) are big fans, and they come highly reviewed.  As I was leaving, I saw Tim Smith just entering the show.  He was headed over to say hello to Kondo-san at Gokiso.  David Marx was home in Nagoya, but told me he loves his Gokiso hubs and that I should check them out.

At the well-manned booth, I was given a demonstration of how perfectly balanced and responsive a wheel can be -- to the point where adding a plastic valve cap would be enough weight to start the wheel rotating.  And they explained how the hubs are designed to avoid damage to the internals, especially the bearings, in both installation and with a suspension to protect from impacts while riding.  They start with ball bearings designed for aerospace applications.

But the cost is a bit much for a mere mortal like me (around $3000 for a set retail).  Great for a show bike, or for Alberto Contador.  Difficult for me to justify.  And as my instructor said at my UBI framebuilding course in February, "we are not flying these things to the moon" ... Bicycles really do not require aerospace precision.

3.  Randonneur bikes at Grand Bois.  I must be getting older.  Or maybe it is just that I have lost what remained of my interest in bike racing following the Lance Armstrong USADA report.  Instead of checking out the latest racing models from Pinarello and the latest in carbon deep wheels, I found myself drawn to the Grand Bois booth.  Grand Bois is a brand of classic and retro bikes and components developed by I's Bicycles in Kyoto.  I think Jan Heine/Compass Bikes handle their products in the U.S.  They had a classic Rene Herse bike from way back (1950s?) on display.

Grand Bois hubs -- retro styling, but modern internals and the convenience of QR skewers.
4.  Different bikes, New bikes.  There were plenty of folding bikes, some belt drives, some wooden handmade bikes, and a modern looking design with the front and rear lights integrated into the top tube ... nice fashion accessory, though not sure I could see myself riding it.  The folders and the belt drive looked like the wheel bases were too short for me.

Strida, the only belt drive model I saw ... though there were probably more. (You need a monostay, like this, or a notch in one side of the seat stays, to fit a belt drive onto a bike).  A UK brand, apparently.

Internal gear Sturmey Archer rear hub.  Dynamo front hub, both with drum brakes.

5.  Handmade bicycles.  Cycle Mode now has a special area for framebuilders, and around 8 to 10 of them had their wares on display.  There was also a stage set up for a presentation by the builders.  Of courser, Cherubim had a display.  It was not crowded, so I took the chance to say hello to Shin-ichi Konno, one of the most celebrated framebuilders of his generation and winner of the NAHBS "best in show" award twice in recent years.  And there was a display for a new vocational school -- Tokyo College of Cycle Design, that opened this year.

Nagasawa-san, the Keirin builder, was there.  As were others.  I liked a bike on display by a Kyoto-based woman framebuilder, Yuka Kitajima.  It was a touring bike with the racks designed for carrying food and drink to a picnic -- wine glasses, tabasco sauce etc. on board.  The steel frame had some very nice etching, and the front rack/fender support was hollow for storage of a spare spoke.  Not that practical, but fun.

Spare spoke fits inside the fender attachment.
I rode my bike about 20 kms to Hacchobori, then put it in the bag and hopped the Keiyo Line the rest of the way out -- a fast way to get to Makuhari.  On the way home, I rode the entire way.  It was about 50 kms, taking Route 14 most of the way from Makuhari into Tokyo.  I needed to hunt a bit for a decent route as I got closer to Tokyo, but it was tolerable, and good for future reference.  ... since I might even go back to Cycle Mode next year.

Sunday Ride -- Yanagisawa

We will ride on Sunday and, given perfect autumn weather, try to get in some distance.

Jerome is staying with Stephen out in Oume (Ikusabata) overnight, so the main rendezvous time/place will be at 10:00AM at the Kori 7-11 convenience store (where Yoshino Kaido cross to the North side of the Tamagawa and ends, about 10 kms beyond Oume).

I will leave my house and pass the corner of Komazawa Dori and Kanpachi at 7:30AM.  It is almost 60 kms to Kori, so you might plan to show up a bit early (7:25) if you want to go out together.  No "15 minute rule" this time.  Leave at 7:30AM sharp (which means no later than 7:35AM).

Here is the planned route to Kori -- drop me an email if you want to meet us somewhere mid-way, so we will look for you.

Or you can take a train to Oume Station and, if you actually leave from there by 9:30, you should be able to get to the rendezvous point in plenty of time.

From Kori, we plan to go over Yanagisawa Pass, which seems somehow to have become Jerome's favorite climb.  Jerome might want to try Odarumi Pass for a second act, since he will have fresh legs from his Oume start ... or maybe Kamihikawa and/or Sasago.   I will take a bike bag since, given those distances, I expect to hop a train home from somewhere in the afternoon, even if I do make it over a second (or third) pass.

Hard Ride

Jerome and I successfully completed the Kanagawa October 6 (to 7) 600 kilometer Brevet.

It was a very hard ride.  8000 meters of climbing or a bit more, with plenty of steep hills even during the last 100 kilometers back into Tokyo.

We finished just after 10PM Sunday evening, 38 hours after the start and about 2 hours slower than other 600km events I have done in the past.  When we finally left the finish area for the drive home about 45 minutes later, the tally remained:  7 finishers, 12 DNFs, and 6 riders still out on the course, with another 1hr 15min left in which to make it back.

Audax Parisien has recently established a new category of event, the "Super Randonee 600".  These are rides of 600 kilometers, with at least 10,000 meters of climbing.  Completing one is now required in order to get one Audax award.  But the Super Randonee 600 events have a 50-hour time limit, instead of the usual 40 hours for a 600 km Brevet.  A good idea.

The weather on Saturday was good.
The weather on Sunday was even better.

The problem was in-between.  It started to rain around 6:30PM Saturday and did not stop completely until Sunday morning around 8AM.  So we were in rain, dark and cold for the climb from Chino up to Lake Shirakaba in Tateshina area, over Daimon Pass (approx Elev 1450 meters) and down a valley to around 600 meters elevation ... and once more back up the North side of the same pass.  This stretch, and the aftermath of riding wet through most of the night to get to the next checkpoint and far enough of schedule for some decent sleep ... claimed most of the DNFs.

I did not get any photos, but the climb up Route 71 through Asakiri Kogen and Kami Kuishiki Mura, was beautiful.  Likewise the village of Saihara on the way up to Tawa Pass and Tsuru Pass -- idyllic Japanese village life, with the crops ready for harvest and the trees just starting to turn colors.
