| 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 others.
The machined aluminium cups hold full 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 madeby
INA and have been designed to run directly on the
crankset axle, without the use of shims or spacers -
again increasing life and reliability.
Hope 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 mm shell width
