Well, back to...Track hubs on road NOT engineering. Just for some reference and warning after removing and cleaning my Suntour Superbe Pro/Deep V wheels I noticed something. The hubs, front and rear, had cracked (even broken free on the front) in at least 10 spoke holes each. Rear was 3x front was radial both 32 hole. The real sad part is the bearings still feel awesome even after the winter thus far. So, for bearing and seal quality, Suntour Superbe Pros seem to be VERY good. Save 'em for the track though....
