Giant Fathom 1 27.5" Mountain Bike (2019)
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. 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+ 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.
