High-quality, CNC machined aluminium external bottom bracket cups with double sealed stainless steel bearings. Version for Fatbike Cranksets with longer 24 mm spindle.
The machined aluminium cups hold full stainless steel cartridge bearings in stainless races. These custom Swiss made bearings are double sealed and fully serviceable to offer a much greater life span than stock units. If they wear out eventually, they are replaceable. The bearings are made by INA and have been designed to run directly on the crank spindle, without the use of shims or spacers - again increasing life and reliability. Hope uses a non contact, free running labyrinth seal to protect the bearing externally, and the machined aluminium center tube is sealed internally with o-rings.
The unit fits frames with a 100 mm wide BSA bb shell.
Delivery includes 3 spacers (2,5 mm).
