Top Features of the Crud RoadRacer Mk2 Mudguard Set Weight: 180g Material: plastic Mudguards designed for road bikes with little clearance between bottom of brake calipers (arch) and top of the tyres. In response to numerous requests the boffins at Crud have re-designed the RoadRacer by extending the rear Roadracer mudguard to give full coverage for the chainset area. They have also beefed-up the product in several key areas for added longevity.
