Hope Bottom Bracket Stainless Bearings 68/73mm


Description : The external bottom bracket with stainless steel bearings. All common systems are covered with this upgrade unit - making it ideal for Shimano, Race Face, Truvativ (extra conversion kit required) and others.

The machined aluminium cups hold full stainless steel cartridge bearings. These custom, Swiss made bearings are double sealed, fully serviceable and removable which give much greater life span than stock units.

The bearings are made (as all our bearings are) 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.

We 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.

The unit is suitable for 68 & 73mm shell width’s - with an 83mm width version and a specific road unit also available.

Standard 6 colours are available on cups - red, blue, silver, black, gold and gunmetal, with the centre tubes being black.


“we’ve had our BB running since November through a seriously wet and nasty northern winter - easily enough to kill most other external BB’s. The Hope is still spinning silk smooth with no hint of play, grind or grumble” MBUK
