Hope’s highly anticipated external bottom bracket is available
with two different bearing options. Many of the common cranksets
are compatible with this bottom bracket - including Shimano,
Race Face, FSA and others (not Truvativ or SRAM).

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, fully
serviceable and removable which give much greater life span
than stock units.

The bearings are made by INA and have been designed to run
directly on the crankset axle, without the use of shims or spacers,
which increases their life and reliability. A non contact, free
running labyrinth seal is used to protect the bearing externally,
and the machined aluminium center tube is sealed internally with
o-rings.

The unit is suitable for 68 & 73mm shell width’s. Standard 6
colors are available on cups - red, blue, silver, black, gold and
gunsmoke, with the center tubes being black on the stainless
and gunsmoke on the ceramic.
