Topeak's Defender XC1 2-Piece Front Fender is a two-piece moto-inspired fender that attaches to suspension fork lowers for a close fit with excellent spray protection. It uses a precision clamp that secures the fender to the lower legs with a special safety feature which allows it to disengage if a large obstruction enters the wheel preventing front wheel lock up. Lightweight impact-resistant plastic provides durability without weighing the front end down and the underside is polished to prevent buildup and aid in cleaning. The quick release attachment fits 36 to 48. 5mm fork legs and the Topeak Defender XC1 2-Piece Front fender measures 13 x 24 x 19 cm.
