101??? never seen those, not seen that even in the catalogs. Either way, i doubt the bicycle will notice a difference of half of a millimeter in the driver side if you put a 102 BB shell in there.

Hey Op what are u trying to do??? That could help a lot. My only guess is a fixie and even with fixies from 102 to 111 are around 3 mm per side, the chain won't notice.
