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

|Weight||The 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 our bikes are designed for best-in-class weight and ride quality.|
