Bump this 'ish, I just got a BK from a seller off CL a bit ago, and it's a blast. It has some old Campy victory cranks on it with a peculiar BCD (106 I believe). It now has a 42t chainring, and there are only 42t,52t,and 53t rings made for this particular crank. I wanna ride a 46/17, so I'm looking for a somewhat cheap solution. I've been looking at the either the andel cranks or some sugino RD's, but I dunno if I should hold out and get some nicer cranks. Also, I don't know what kinda of BB is ideal for the BK. Any help is appreciated!
