My 1988 Victory cranks used the same BB spindle length as early C-Rec - I ran a C-Rec BB for a long time with these cranks. 109 mm according to Campy. I believe that later, Campagnolo added 1 mm on each side to allow the use with wider chainstays. -- Jan Heine, Seattle Editor/Publisher Vintage Bicycle Quarterly c/o Il Vecchio Bicycles 140 Lakeside Ave, Ste.

Don't the Victory cranksets uset the same bottom brackets as
the later NR/SR cranks? If that's the case, a 115mm
spindle/cup set - either NR (thick wall cups) or Gran Sport
(thin wall cups) should work.
