Giant Fathom 1

Overview

Get your dose of singletrack on a fun hardtail that puts you in control. The combination of a lightweight hardtail frame, 130mm suspension fork and 27.5 wheels with wide rims and high-volume tires delivers loads of traction, speed and fun on the trail.

With its updated ALUXX SL aluminum frame, quick-handling 27.5 wheels and high-volume tires, 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 frame is designed with trail-friendly geometry that includes a more relaxed head angle and a 130mm 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. All our bikes are designed for best-in-class weight and ride quality.
