All common systems are covered with this upgrade unit – making it ideal for
Shimano, Race Face, FSA 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 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.

A non-contact, free running labyrinth seal protects the bearing externally, and the machined aluminium centre tube is sealed internally with o-rings.
