Wheel No. 28 Redux

I had built up Wheel No. 28 in December of last year but have not used it yet. My 10-year old Ti Travel bike frame needed a repair to the seat tube due to a boneheaded move (I overtightened the front derailleur clamp). It is repaired, but I am waiting for it to get shipped back from the factory (in another larger shipment of frames). Welcome to the supply chain issues of 2022!

Meanwhile, I was able to secure a DT Swiss RR411 32-hole front rim that would match the RR411 rim I used for the rear Wheel No. 27.  The rear one is asymmetric, to allow slightly more even tension between drive and non-drive side. The front rim is symmetric. I decided to take the new spokes and rim off Wheel No. 28's H Plus Son Archetype rim and rebuild it with the DT Swiss rim instead. Why? Of course, the aesthetics favor a matching front and rear rim. More important, RR411 rims are "tubeless ready" while H Plus Son rims are not, and it makes sense that both front and rear rims have this designation, as I will eventually try them with a tubeless set up. Finally, at around 930 grams w/o QR skewers or rim tape, this is around 25 grams lighter than my previous lightest dynamo hub front wheel, with a 370 gram hub and 32 triple cross (Sapim CX-Ray bladed) spokes. The RR411 is probably not as strong as the H Plus Sons Archetype rim, but I expect it will hold up just fine.
