I had Rich build me a set of wheels on XT hubs and Dyad rims. 36h, both front and back; wanted it to have less weight and tension per spoke, but still a strong rim at that spoke count. Per Grant's aforementioned explanation, I was wanting unmachined; so Rich and I talked a good while about machined versus unmachined. But in checking, he couldn't get Dyads that were unmachined at the time, we had to go with machined instead. However, he said a machined Dyad is plenty strong, stronger than most other unmachined rims (unmachined Synergies, for example). I don't have a ton of miles on 'em yet, just built the bike in March. I did twenty-five miles on the first of the April, then the next day I did 35 miles on the Creeper trail (Abingdon to Damascus and back). Just some shorter rides last weekend with my daughter at Steele Creek (~5mil each), and just a couple of miles w/ the family this past weekend. Last night my son and I did 15mi on the Greenbelt. I'm runnin' 32 Paselas, no problems yet. Oh, and I was at 255 at Christmas, I'm down to 233 now, my initial goal is, 199... still a ways to go.... -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
