The XLC bike mirror MR-K21 is the ideal choice for the safety-conscious commuter who wants to know what’s happening behind their back! Made with flat, riser or commuter bars in mind, the inner clamp expands to fit a range of internal diameters from 14.8 mm to 22.5 mm for a secure fit. The 3D adjustable, shatterproof mirror can rotate a full 360 degrees and be folded out 180 degrees meaning the rider can see the full span of traffic behind them. As well as this, the included reflector will keep you as visible to passing traffic as they are to you. Keep yourself safe on your commute to work and be aware of your surroundings, thanks to the MR-K21 bike mirror.
