Overview

About this bike

Get your dose of singletrack with more confidence and control. The combination of a lightweight hardtail frame, 120mm suspension fork, and 27.5 wheels with wide rims and cushy high-volume tires delivers loads of traction, speed and fun on the trail. With its lightweight ALUXX SL aluminum frame, 27.5 wheels and high-volume tires, the new 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 tires that absorb bumps and give you more traction—so you can tackle rougher trails with total control. The new frame is designed with trail-friendly geometry that includes a more relaxed head angle made for a 120mm suspension fork. Proven alloy performance ALUXX SL aluminum frameset is hand-built in-house by the world leader in aluminum engineering. Traction and stability Frame geometry is designed to optimize the confident, stable handling of 27.5 wheels with plush high-volume tires—ideal for rugged, adventurous terrain. Trail tuned More relaxed frame geometry (compared to XC) and control-focused components deliver added control for trail riding conditions.
