The MUTT uses a reinforced frame construction developed specifically for the demands of street and competition trials. The rear triangle and head tube area feature dedicated reinforcements, while guided internal cable routing keeps the frame clean and functional.
The frame is compatible with both HS rim brakes and disc brakes. Campmajó Bikes’ modular dropout system allows different disc brake mounts to be fitted for 160, 180, 200 or 203 mm rotors, with 180 mm supplied as standard.
A custom one-piece bottom bracket and chainstay junction is designed around the AS30 standard commonly used in competition trials, allowing the use of dedicated trials cranksets and bottom brackets such as Clean Trials or WAW. Together with the dedicated rear yoke and reinforced frame construction, it provides the stiffness and durability required for high-level trials riding.
