The ADHDSDF front fender features a split design that allows for the installation of just the front, rear, or both. Quick installation is achieved using the SPEED click adapter, which screws into the fork stem. The spacers fit holes with diameters ranging from 18 to 36 mm, and also fit 1.5 forks. Additionally, the contact surfaces are coated with a flexible material to prevent slippage in the hole. The ADHDSDR rear fender features all the benefits of the award-winning SIMPLA HAMMER fender. It fits any type of bike, and quick clamp adjustments make it easy to adjust to any seatpost diameter (from 25 mm to 35 mm). The proven fork design and double pivot allow for a perfect fit of the fender to the ergonomics of the frame and wheel. The wide fin, made of high-impact plastic, provides maximum protection while riding on any terrain. Furthermore, the use of flexible plastic reduces the fender's weight. A reflective element is located on the rear section to improve the rider's visibility.
