Overview
About this bike
Gateway to singletrack. Get your dose of singletrack on a fun hardtail that puts you in control. Climb, corner and descend with confidence. With its lightweight ALUXX SL aluminum frame and trail-friendly geometry, Fathom is a great choice for XC terrain and singletrack shredding. It blends the efficient ride quality of a classic hardtail with the can-do capabilities of an all-round off-roader. Engineered to optimize its 27.5 wheel platform, it has trail-friendly geometry including a more relaxed head angle made for a 120mm suspension fork.
