Read well these
basic info before ordering the parts.
Bearing replacement is not an easy operation as it may seem.
Additionally the installation of any kind of Ceramic bearings requires a very
good specific expertise.
Extralite offers complete tool-sets for hub maintenance: the Pro-tool kit
1 and Bearing-sitter includes bearing inserting tools in every bearing sizes
used on UltraHubs / HyperHubs / CyberHubs.
If your hub was originally equipped with standard bearings it will probably
require micro-tolerance adjustments to axle and bearing fittings, this
to allow proper bearing rotation and durability (these operations are for
real experts only). Alternatively send your hub to us for this servicing.
