Spoke Protector

The humble spoke protector can save your spokes, derailleur and frame. We fit them when we can to basic utility bikes when there is a chance of misadjustment or minor bending being overlooked by the bikes' owner, reducing the chance of the rear derailleur getting hooked up and mangled in the spokes.

Shimano CP-FH56 spoke protector for 32 spoke wheels and maximum sprocket size 34T. Diameter: 190mm.

Shimano claims this guard works with their light alloy sprocket carrier cassettes (XT type). We've found that with some hubs (non-Shimano) there's a bit of interference between the carrier and the spoke guard. A thin shim (half millimetre?) inside the cassette can get around this. Note - a spoke protector is not meant to be used with the latest generation of XT cassettes which have studs at the back to catch an overshifted chain. Weight: 45g.
