Get your dose of singletrack on a fun hardtail that puts you in control. Featuring new 27.5+ wheels and tires, Fathom helps you climb, corner and descend with confidence.

With its lightweight ALUXX SL aluminum frame and new 27.5+ wheels and 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 plush 27.5+ tires. The larger tires 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.
