the correct crank for that BB? or the correct BB for the 7600 crank? your question is kind of unclear.

IF you are talking about the DA cranks, I've used a Sugino 75 and a Hatta BBs with them. If you are talking about the BB, I've used Sugino 75s with it. Funnily enough I never ended up with DA on DA, but never had any problems with any of those combinations.

Well, the DA 7600 crankset and the corresponding DA square taper BBs (the older loose ballbearing 7400 one and the sealed 7610 one) are all ISO taper. So either of these combos would be a perfect match, obviously.

But like Nate I'm currently using a Sugino 75 bb with the DA 7600 cranks and DA HF track hubs and the chainline is perfect.
