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,

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
