Center Hubs Road Bike Hub Disc Brake SR315

Simple Maintenance

Our hubs are also known for the notool technology. We also found a way to further improve this system and make maintenance even simpler, by a small change of the endcaps.

Freehub Body Conversion

Simplified due to easier disassembly.

Less Weight

Not only the reliability improved. The fusion of ratchet and threaded ring reduces the number of single parts of the system what offers an important advantage.

Less Wear

A single cylindrical spring ensures faster full engagement and thus increases reliability.

Superior Reliability

The full engagement of the ratchets creates a large contact surface and therefore low surface pressure that leads to superior reliability.

Increased Bearing Lifetime

The integration of the bearing into the threaded ring allows the bearing distance to be maximized. The increased distance further supports the axis, which results in less deflection of the axle and thus protects the bearings and increases their lifetime.
