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

▶With its lightweight ALUXX SL aluminum frame and new 27.5 high volume 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 high volume 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.

Key Performance Factors

Proven alloy performance

ALUXX SL aluminum frameset is hand-built in-house by the world leader in aluminum engineering.

Traction and stability

Frame geometry is designed to optimize the confident, stable handling of 27.5 high volume tires, and is ideal for rugged, adventurous terrain.

Trail tuned

More relaxed frame geometry (compared to XC) and control-focused components deliver added control for trail riding conditions.

WeightThe 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 Giant bikes are designed for best-in-class weight and ride quality.
