TdF 5.5 Hubset

A step above the TdF 4.4 hub platform, the 5.5 features ceramic bearings in the hubshell for even more weight savings. Proprietary hubs, designed and manufactured in the USA. The front hub has a unique 85mm wide flange placement which increases the lateral wheel stiffness by nearly 20%. The rear hub features our Patented Differential Flange Diameter, which doubles the number of pulling spokes and creates a more durable wheel. Both feature oversized axles, increasing the wheel durability and stiffness without increasing the wheel weight.

Freehub: CNC machined Titanium freehub body has 3 independently sprung steel pawls for a bomb-proof torque transfer system. This system is strong, simple and dependable. Shimano/SRAM or Campagnolo 10/11-speed compatible.
