A lightweight hubset designed expressly for the demands of road racing.

The R45 hubset is 20% lighter than our Classic hubset. We designed sleek new hubshell bodies and new 17 mm axles. That's 17 mm from dropout to dropout resisting deflection during cornering or when the power is full on. We designed a driveshell with a twin bearing design that responsibly removed as much weight as we could from the inner components. Even our patented RingDrive engagement system was redeveloped resulting in a quiet, fast-engaging 45-tooth stainless steel system unique to the R45 rear hub.

We make our own ceramic bearings and we build them to the same exacting standards as our 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. We build our ceramic bearing R45 hubs with a very small amount of silicone-based lube for a system with very low drag. Take advantage of our user-serviceable bearings and run minimal lubrication for the ultimate in race-day performance.
