2020 Giant Fathom 2
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.

Weight The most accurate way to determine any bike’s weight is to have your local dealer weigh it for you. Many brands strive to list the lowest possible weight, but in reality weight can vary based on size, finish, hardware and accessories.
