Crank up steep climbs with smooth-rolling efficiency. Swoop down singletrack descents with stability and speed. This aluminum hardtail 29er features progressive trail geometry, a plush suspension fork and dropper seatpost for the confidence you need to up your singletrack game.

Built on an ALUXX SL aluminum frame, the Fathom 29 features updated geometry that produces a stable ride quality for challenging XC trails. The frame is optimized for a 130mm suspension fork for smooth control on the descents. An updated Giant WheelSystem comes with tubeless tires already set up, making it easy to experience added efficiency and control, plus a reduced risk of flats on technical terrain.

Key Performance Factors

Trail Tuned Design

Balanced geometry with a 75-degree seattube angle puts the rider in a powerful pedaling position on the climbs, while a slacker 66-degree head angle boosts confidence and control on technical descents.

Responsive Handling

Lightweight ALUXX SL aluminum hardtail frame offers agile acceleration and maneuverability to help riders climb, corner and hammer the flats with efficiency and speed.

Smooth Control

Giant Crest 34 suspension fork with 130mm of travel absorbs roots, rocks and ruts. Grippy, high-volume tires boost traction on rugged terrain. And a dropper seatpost with handlebar remote lets you adjust saddle height on the fly for confident positioning on changing terrain.
