American style eccentric BB to BSA adapter


Current stock: 0

For use with BBSHD or BBS02, likely other mid drives as well (i.e. Cyclone)

Turns your American style Eccentric bottom bracket into standard BSA

Price is for a set, enough to do one mid drive installation (or conversion to BSA standard for any other purpose)


These adapters were produced by request due to popular demand for a solution allowing the ability to mount mid drive motors onto American bottom brackets, sometimes referred to as Ashtabula BB.

See this link for more info on Ashtabula

Installation note: When measuring to pick out your motor with this adapter on your BB shell please measure the total width including any width the adapter adds.
So if it adds a couple millimeters on each side take that into account. For a BBSHD this is less of an issue than BBS02.
