Unusually Large Eccentric BB shell
Hello,
I recently bought a steel single speed frame designed for an eccentric bb from 2009. It’s originally from a shop here in Ottawa that used to sell them under their own brand. They have a great reputation and I know it’s a good quality frame.
when I brought it home I started measuring aspects of the frame to start ordering parts, however I quickly noticed I couldn’t find an eccentric bb adapted that seems to fit the frame. The bb shell inner diameter is about 62-63mm, but I couldn’t seem to find anything that fit larger than 57mm, let alone any information at all about larger sized eccentric bottom brackets. Has anyone seen this before? Any suggestions where I might find a suitable part?
