I think it depends on whether you're talking about the square tapered kind, or the splined kind of
BB. The new splined BB is 109.5mm, the old square tapers were 103, 107, 110, and 115mm, and longer.
He just grabbed the wrong kind, that's all.

Mike,

Thanks for the info! I was looking for splined BBs. That makes sense.

Nope not for splined shimano cranks..110mm was probably a square taper...ahhh the stuff that goes on
in some bike shops...if they were car parts stores they would be outta biz...
