HOPE MTB bottom bracket PF41 - 104.5 / 107 mm stainless steel bearing
It is common knowledge that it rains a lot on the "island". The Brits at Hope have set themselves the task of developing a bottom bracket that resists any influence of nature.
The basis are bearing shells and a center sleeve made of CNC-milled aluminum. O-rings between the center sleeve and the bearing shells prevent water and dirt from entering the inside of the bottom bracket via the frame. Stainless steel ball bearings, which are manufactured for Hope in Switzerland by bearing specialist INA, rotate in the bearing shells. The ball bearings are double-sealed and are additionally protected by a labyrinth seal. The updated version of the bottom bracket is suitable for 30 mm shafts and has specially developed bearings.
Note: Shafts with a diameter of 28.99 mm can also be used with the adapters supplied.
