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. KEY PERFORMANCE FACTORS Proven alloy performance - ALUXX SL aluminum frameset is hand-built in-house by the world leader in aluminum engineering. Balance 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.
