Hybrid street trial frame - Mind Control MUTT 26"

Hybrid street trial frame - Mind Control MUTT 26"

The MUTT is a 26" street trial frame developed by Mind Control Trials to bridge the gap between pure street riding and competition trials.

Designed around a street trials fork, but with a frame geometry that blends elements of both street and competition trials, the MUTT brings a more aggressive, competition-inspired character that makes technical moves feel more natural, while retaining the playful handling, spins and freedom of movement that define a true street bike.

Developed by Mind Control Trials, tested by world-class riders Charlie Rolls and Samuel Lavaty, and manufactured by Campmajó Bikes in Catalonia, Spain.

The MUTT geometry combines the playful handling of a street trials bike with a more aggressive, competition-inspired riding position. Built around a 26" street trials setup and a 415 mm fork with 30 mm offset, its geometry is designed to make technical trials moves feel natural while retaining the agility and freedom needed for spins, street lines and creative riding.

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.
