Chain Wheel Cover 42T 10.4cm Pitch

This black plastic guard fits a 42 tooth chain wheel with a 10.4cm pitch and four mounting holes. It shields the chain from scratches and prevents clothing or legs from catching on the teeth. The universal design suits mountain bikes and road bicycles alike.

Simple Screw Mounting

Five plastic screws are included for a straightforward bolt-on installation. Align the four 3mm holes with the chain wheel and tighten each screw by hand or with a basic tool. Over-tightening can strip the plastic threads, so stop when the cover sits flush.

Verify Chain Wheel Specifications

Confirm your existing chain wheel has exactly 42 teeth and a 10.4cm pitch before ordering. Measure the hole pattern to ensure four holes at 3mm diameter match the cover. The guard will not fit other tooth counts or pitch dimensions.

Questions about this item

How do I confirm the 42T chain wheel cover is seated correctly after tightening the supplied screws?

The cover should sit flush against the 42-tooth chain wheel with no visible gap around the 10.4 cm pitch circle; all four 3 mm mounting holes must align and the five included plastic screws should hold the 1.6 cm thick guard firmly without wobble.

What components are included and is any extra hardware required for installation?

The box contains one black plastic chain wheel cover measuring 18.9 cm in diameter and five plastic mounting screws; no additional tools or fasteners are needed.

Which version should I choose if my chain wheel has a different tooth count or hole pattern?

This model is made only for a 42-tooth wheel with four 3 mm holes on a 10.4 cm pitch; if your crankset differs in tooth count or bolt layout, this cover will not fit.
