The eagerly anticipated external bottom bracket is
now available, with two different bearing options. All common systems
are covered with this upgrade unit - making it ideal for Shimano,
Race Face and others.
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 (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 aftermarket 83mm tube’s available where required. A
road specific unit will follow. Standard 6 colours are available on
cups – red, blue, silver, black, gold and gunmetal, with the centre
tubes being black on the stainless and gunsmoke on the ceramic
