A practical choice for commuters, casual riders and mountain-bike users who want quick, removable front splash and frame protection across a wide range of bike sizes.
The Deflector FC50 is a universal front mudguard and frame protector for adult and children’s mountain bikes, city bikes and hybrid bikes. It sits discreetly beneath the down tube and helps shield you from rising water, mud and stone projections, while also protecting the frame from debris.
Installation is straightforward: the MD-Quick system uses two 165 mm elastomer straps that fit down tubes up to 75 mm in diameter. You can fit or remove the guard without tools, making it useful when weather changes or when you want a cleaner-looking bike for dry rides.
Compatibility covers 24, 26, 27.5, 28 and 29-inch wheels with tyres up to 3.0 inches wide. The polypropylene guard measures 340 × 80–60 × 35 mm and offers a minimal protection level—a compact, practical solution for everyday riding rather than full wet-weather coverage. Check that the mudguard is tight before each ride.
