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.

Trail Tuned Design Balanced geometry with a 75-degree seat tube 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.
