Topeak DeFender RX

This fender is designed specifically for mountain bikes with 27.5-inch or 29-inch wheels. Because it uses a universal strap mounting system, it is compatible with most seatpost diameters and frame geometries.

The fender uses an endless strap system that wraps securely around your seatpost. You can tighten or loosen it by hand, allowing you to install or remove the fender in seconds without needing any tools.

Yes, the DeFender RX features an adjustable rear angle. This allows you to pivot the fender to better match your bike's frame geometry or to provide more coverage depending on your riding style.

The fender is constructed from injected molded nylon, which is both lightweight and impact-resistant. It is built to withstand the vibrations and debris common on technical singletrack without cracking or adding unnecessary weight.

At 558.8 mm in length and 101.6 mm in width, it offers substantial coverage for larger mountain bike tires. While no fender catches 100% of trail spray, this model is highly effective at blocking the majority of mud and debris kicked up by the rear wheel.
