Get your dose of singletrack on a fun hardtail that puts you in control. The combination of a lightweight hardtail frame, 130mm suspension fork and 27.5 wheels with wide rims and high-volume tyres delivers loads of traction, speed and fun on the trail.

With its updated ALUXX SL aluminium frame, quick-handling 27.5 wheels and high-volume tyres, Fathom is a great choice for technical terrain and singletrack shredding. It blends the efficient ride quality of a classic hardtail with the confident ride quality of larger tyres that absorb bumps and give you more traction – so you can tackle rougher trails with total control. The frame is designed with trail-friendly geometry that includes a more relaxed head angle and a 130mm suspension fork.

Key Performance Factors


Trail Tuned Design

ALUXX SL aluminium frameset is hand-built in-house by the world leader in aluminium engineering.

Responsive Handling

Frame geometry is designed to optimise the confident, stable handling of plush high volume tyres (27.5×2.6), and is ideal for rugged, adventurous terrain.

Smooth Control

More relaxed frame geometry (compared to XC) and control-focused components deliver added control for trail riding conditions.
