Dura Ace 7600 Bottom Bracket
 

Alright. I know there has been alot of talk about the correct bb for this crankset, but can anyone tell me what you are running?

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.

I guess my questions is weather it is JIS or ISO

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.

isn't this always* the question...

My heads going to explode.

why don't people just use the bb that is designed for the cranks ?

because the 7610 bb is somewhat hard to find these days...
