The ultra lightweight R45 hub has been designed expressly for the demands of road racing with two objectives. It must be light an fast.
The R45 front hub is 12 % lighter than a Classic hub. Because Chris King has designed a sleek new hubshell body and a new 17 mm axle. That's 17 mm from dropout to dropout resisting deflection during cornering or when the power is full on.
Furthermore Chris Kings designed and build the ceramic bearings to the same exacting standards as their classic, time-tested stainless steel ball model. Pairing the corrosion resistance of ceramic balls with our proven sealing system allows for greater flexibility with greasing options. In addition the ceramic balls are lighter, harder and have a greater roundness than stainless balls, for a bearing with exceptional speed and strength.
Clearance: R45 Front can be used with radial lancing.
