HOPE Stainless Bottom Bracket 68/73mm
|Options||68/73mm Black BBSSXCN In Stock|
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.
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 and 73mm shell widths - with an 83mm width version and a specific road unit.
Standard 6 colours are available on cups - red, blue, silver, black, gold and gunsmoke, with the centre tubes being black on the stainless and gunsmoke on the ceramic.

Hope bottom bracket review, MBUK magazine:
"We've had our BB running since November through a seriously wet and nasty northern winter - easily enough to kill most other external BBâ€™s. The Hope is still spinning silk smooth with no hint of play, grind or grumble"
