Using the Zefal Deflector RS75 is easy. First, use the MD - FIX System to mount the mudguard on your bike. Make sure to adjust it accurately with the double - adjustment feature. The mounting system can fit bike parts with a diameter from 16 to 42 mm. This mudguard works great on all mountain bikes, especially those with suspension. When riding, it will protect you from mud and debris. For maintenance, just clean it with water and mild soap after a dirty ride. Store it in a dry place when not in use. Keep in mind that although it's designed for 27.5 wheels, it might work on similar - sized wheels too, but performance may vary.
