Shimano PF41 BB92 89.5-92mm to BSA adaptor for BBSHD

Finally! An adaptor to allow the Bafang BBSHD mid drive motor to fit into Shimano PF41 BB92 bottom bracket shells. This is a 2 piece adaptor machined from 6061 aluminum. Its 2 peices for a reason allowing it to fit in both smooth bore PF41 shells and the shells with flanged bore. We recommend using the 100mm width BBSHD motors with this adaptor. Now you can finally install the amazing mid drive into your modern full suspension mountain bikes, or any alloy frame bike you desire with the Shimano PF41 bottom bracket shell. Carbon frames with press fit are too thick to allow BBSXX motors to fit. Works with aluminum frames only. More info seen here.
