Well, I've personally built several disk wheels & a couple of those were fronts and will be building 2 or 3 more shortly. (On top of that I have probably built a couple dozen non disk wheels) No disrespect to Rich but the front disk hubs I have used required no dish at all! Typically, (from what little I've seen) the manufacturers relocate the non braking side flange further inboard so that no dishing of the wheel is needed and while I prefer not having any dish in the wheel I am not sure whether I wouldn't prefer it to the loss of triangulation that results from moving the flanges in to compensate for the disk. I used the term sprung weight mearly as a counterpoint to the rolling weight and because a better term did not come to mind. It was not the significant point of the topic anywayz. The main point that you obviously missed was that less rotating mass is preferable to less weight in the frame. AND not to be argumentative or go into too much pointless explanation, but a bicycle frame on spoked wheels would be considered sprung weight! Your friends Trek probably just got a bum wheel, my XO-1s front wheel broke several spokes when I first got it, tore it down rebuilt it, no further problems. The average rider probably doesn't break too many spokes regardless of configuration, which was part of the point of what I was making. If you break a lot of spokes you need a new wheel builder.
My experience with trying to straighten pieces of metal like brake rotors is that typically you do more harm then good. The tolerances on disks are so small that a wobble of less then a millimeter effects whether it will rub or not and by extension how good it will work. I have seen people "shrink" metal, using a torch/heat, but again I might cause more harm then good. -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
