The XLC spoke reflector CR-S01 is a handy bit of kit to increase your visibility in the dark from the sides. You may already have front and rear lights and reflectors, but can drivers and other road users see your side on? These spoke reflectors work by clipping onto the spokes of your wheels and providing this extra visibility from the sides. Each item comes with four pieces, enough to attach two spoke reflectors to each wheel. The XLC CR-S01 spoke reflector is compliant with road traffic regulations for all bikes and can be used on many different types. This includes but is not limited to mountain, road, city, race and trekking. Be seen in the dark with these spoke reflectors.
