Phil Wood introduced the now-standard Field Serviceable Axle (FSA) in 1991. The FSA design enables the axle to be separated from the hub after unthreading the end caps using two hex wrenches. The quick release axles use a 5 mm hex wrench and the bolt axle hubs use an 8 mm hex wrench. Our axles are threaded externally, with the end caps threaded to exactly match the axle thread. The hubs use shouldered axles that precisely position the bearings.

The Field Serviceable Cassette (FSC) design enables to you to remove the axle (as in our FSA hubs) and easily perform maintenance on both the hub bearings and the Phil freehub body mechanism. Our freehub body is 8-, 9-, and 10-speed Shimano compatible. The axles are precision ground to 15 mm in diameter. The hub shells use a unique Hi-Lo flange configuration enabling better balanced spoke tension.

All disc brake hubs use the international standard 6-bolt rotor mounting pattern.

• ROAD, freewheel and cassette rear options
