Built on an ALUXX SL aluminium frame, the 2021 Giant Fathom 29 1 Mountain Bike features updated geometry that produces a stable ride quality for challenging XC trails. The 2021 Giant Fathom 29 1 Mountain Bike frame is optimised for a 130mm suspension fork for smooth control on the descents. An updated Giant WheelSystem comes with tubeless tyres 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 pedalling position on the climbs, while a slacker 66-degree head angle boosts confidence and control on technical descents.
Lightweight ALUXX SL aluminium hardtail frame offers agile acceleration and manoeuvrability to help riders climb, corner and hammer the flats with efficiency and speed.
A suspension fork with 130mm of travel absorbs roots, rocks and ruts. Grippy, high-volume tyres 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.
