Built for BBSHD
Typically this would be used with 100mm BBSHD size as PF41 shells are usually 86-91mm. The added width on the flange where it fits on the non-drive side means that in many cases you will not need to use a lot of spacers. In some instances 120mm may be preferred depending on the application (for example if the chainstay flares out from the shell so it needs additional spacers, or if the PF41 shell is wider than standard).
This adapter provides a standard BSA shell width compatible with BBSHD axles. It is not intended for use with BBS02 or standard sized 68-73mm BBSHD, as the axles on these motors are not long enough for the typical PF41 shell standard. Additionally, the adapter is not threaded on the inside for use with Cyclone.
