Traditional mudguard construction dictates a sturdy design, with bolted fixing at the brake bridges, and or rigid plastic utilised in the main arc. This principle has remained unchanged for a century or more. The Crud Roadracer concept turns orthodox road mudguard design on its head, Crud designers reasoned that if you could 'float' the mudguard off the rim, then you could do away with a lot of the traditional fixings. The Crud Roadracer mudguard (180 grams for the pair) just hovers in place so there is nothing to rattle or rub. The brushed instantly dampen any road vibration, settling the mudguard into it's neutral central position. In extensive tests Crud have failed to wear the pile against the rim, and the friction involved is so light as to be immeasurable.
