Dave Martinez axed:
What size spokes would I need for: -650B 36 hole SuperChampion Mod 58 rims. -FB (3 piece) small flange hubs, 120 spacing. -Cross 3 pattern.
Dave, By Sutherland's 3rd ed.; reference pg 12-4 and 12-9: results will be 293 front and 292 rear. Campy rear flange diameter measured at 52mm. OLD Campy (FB manufacture) measured at 51 cm.; so not TOO much difference.
700c tubular Super Champs would be 300mm.
292 all around should do fine.
