You need UN-xx. Available at your local LBS. Shimano cart bb.

Shimano = JIS

You'll need a 109mm JIS spindle for those cranks. The DA 7600/7610 BB is kinda spendy, but if you can find someone that stocks a 109mm UN-73, you can get one for $40 or so.

yeah I figured that it'd be JIS, it's just that on sheldon's website, he mentioned that japanese njs cranks were often ISO, so I wanted to be certain.
