*****

Fits any PFBB shell with 41mm inner diameter and makes your Bafang BBSxx fit like a glove. 

This is for fat bike owners who our fancy ridged PF41 locking adapter does not work  (the locking adapter is for only 86.5mm). 

If your bike uses the PF41 adapter this press fit adapter will be the perfect converter for you to get your BBSHD to slide right in. 

We custom cut these for the fat bike owners.  

If you need yours cut to a custom size just put in your order notes what size your  BB is and we will cut to fit (1mm less than your BB size).  No refunds or exchanges on custom cut BB adapters.

  1. PF 41 adapter on Rocky Mountain Suzi Q 30

    Posted by Wayne Rasmussen on Sep 1st 2017

    I used the adapter to mount a 120mm BBSHD in this Rocky Mountain Fat Bike. The bike has a BB107 bottom bracket which is 41mm diameter at the ends where the bearings press in but slightly smaller along the mid section of the rest of the bracket. I used a lathe to reduce the adapter diameter to a good press fit using the actual bottom bracket as a guide. The overall bracket width is 107mm so I ordered the length cut to 106mm which worked great.
    Access to a lathe in this case was necessary but starting with this adapter made the final machining to a good press fit a quick project.
