State-of-the-art aluminum frameset material features best-in-class strength-to-weight ratios and unique welding technologies for a high-performance ride quality.
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.
ALUXX SL aluminum frameset is hand-built in-house by the world leader in aluminum engineering.
Frame geometry is designed to optimize the confident, stable handling of 27.5+ tires, and is ideal for rugged, adventurous terrain.
More relaxed frame geometry (compared to XC) and control-focused components deliver added control for trail riding conditions.

This High-Performance level, state-of-the-art aluminum material is made predominantly from 6011 alloy and delivers best-in-class strength-to-weight ratios. These framesets also feature unique welding technologies for a high-performance ride quality.
Giant’s original oversized fork steerer tube technology. Designed to provide precise front-end steering performance, the system’s oversized headset bearings (1 1/4” lower and 1 1/8” upper for road, 1 1/2” lower and 1 1/8” upper for mountain) and tapered steerer tube work in conjunction to provide optimal steering stiffness.
Fewer flat tires. Greater traction. Less rolling resistance and a smoother, faster ride. Giant’s Tubeless System makes it easier than ever to experience all these benefits.
