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