• BBSHD Motor Core (VERSION B)

Not sure which core you need/have?

The bare motor casing should have a sticker or stamp on it indicating what size it is. As to the core, it can be identified by looking at the mount bracket holes on the core. Fatbike cores have very large mount hole brackets, roughly 50mm thick. The regular 68mm cores have thin holes.
