Flascheguard fenders are made from end-of-life water cooler bottles and use up to 75% less crude oil than virgin polycarbonate. 3.2mm 100% Recycled stainless steel support stays. Matte finish has the look of alloy but won�t dent or bend and has a more durable finish. Glossy inner layer finish resists dirt and grime build-up. Extended fender lengths and duckbill mud flaps keep feet dry and eliminate rear spray. Support stays spaced for maximum stiffness and frame compatibility. Compatible with a wide range of suspension fork disc brake and thru-axle equipped bikes. Sold pre-assembled for quick mounting
