I want to put the crankset on a Carver 96'er bike (don't have it yet), which takes a 68mm I think, but I can't find a Shimano techdoc that tells me if I need 113mm or 118mm (or something else).

Sorry if this is a completely naive question.

Also, BB-70 or BB-71? What's the difference?

Thanks for helping a noobie on his first bike build -

Thanks.

I had found that techdoc but since it only lists XT 751 and not 752 I wasn't sure if it would be the same.

Also, how do I know in advance if I need 47.5 or 50 chainline? Will either work?

Thanks again
