Hope Technology Ceramic Road Bottom Bracket 68/73mm Shimano

The external bottom bracket is available with two different bearing options. All common systems are covered with this upgrade unit, making it ideal for Shimano, Race Face and Truvativ (extra conversion kit required).

The machined aluminium cups hold either full stainless steel cartridge bearings, or ceramic bearings in stainless races. These custom, Swiss made bearings are double sealed which gives much greater life span than stock units. They are also replaceable. The bearings are made by INA and have been designed to run directly on the crankset axle, without the use of shims or spacers - again increasing life and reliability. Hope use a non contact, free running labyrinth seal to protect the bearing externally, and the machined aluminium centre tube is sealed internally with o-rings.

These cups are suitable for 68 & 73mm shell width’s.
