I pulled the BB from the Poprad today., BB-6500/68/BC 1.37 x 24 with a length of 109.5. I have done a couple of searches and the only other size I find with 68 English is with a spindle length of 118.5. I also looked for 7700 Dura Ace and no good option with that search. One of the descriptions for the 118.5 states it is for 3 speed FD. Also, to me, that seems like too long of a length from the 109.5. Any help with this would sure be appreciated. If the 118.5 is workable, will this BB5500 be compatible?

More info: The clearance between the inner ring and the chainstay with the 6500 crankset is about 7mm, and with the 7700 it is only 1.5mm. It seems to me that the BB with spindle length of 118.5 should work. If the 5500 BB is compatible, one source I found says it is, I can get a new one for quite a few dollars less.
