A good choice for gravel riders, commuters and MTB users who want a lightweight, tool-free rear fender for tyres from 30–50 mm and up to 55 mm capacity.
The ASB-1 is a rear bicycle fender built for riders who want quick, uncomplicated spray protection. Its minimalist 0.8 mm polypropylene construction keeps weight down to just 25 g, while remaining rugged and weather resistant for regular use in damp conditions.
Installation is tool-free: the FLIP-TIP attachment system securely locks the fender to your saddle rails, including ovalised carbon fibre rails. Slightly perforated folding zones help you pre-form the fender before fitting, so it is easy to keep ready for changing weather.
