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.
HIGHLIGHTS
Built on a lightweight ALUXX SL aluminum frameset with progressive trail geometry, Fathom 29 is designed for the added stability and roll-over capabilities of 29-inch wheels with grippy, high-volume 2.5-inch tires. It has a number of trail-specific features including a 130mm suspension fork and dropper seatpost. Here’s a look at its key technologies:
1
ALUXX SL ALUMINUM
2
CREST 34 SUSPENION FORK
130mm travel fork is engineered with a lightweight twin air spring along with volume spacers to adjust performance for riding style and weight. State-of-the-art machining provides tight tolerances for low-friction fork action, and an adjustable damper system lets riders fine-tune the feel.
3
INTERNAL CABLE ROUTING
Derailleur, brake and dropper post cables are primarily routed internally through integrated ports. This helps saves weight and creates a cleaner look and performance.
4
CONTACT SWITCH DROPPER POST
Durable and hassle-free dropper post uses alloy air and oil cartridge for smooth, consistent saddle height adjustment (125mm for Small, 150mm for Medium, 170mm for Large and XL). Handlebar-mounted remote lever makes it easy to operate on the fly.
5
FORGED CHAINSTAY
New frame design provides maximum rear tire clearance for larger tire sizes. This design also results in a shorter rear-center frame measurement for progressive trail riding performance.
6
29-INCH WHEELS
Larger-diameter wheels and added frame and fork clearance for high-volume tires give Fathom 29 improved balance, stability and speed that’s ideal for smooth, fast singletrack trails.
7
ADDITIONAL BOTTLE MOUNT
Bottle mounts on the underside of the downtube allow Medium, Large and XL frames to carry three bottles. Small frames can carry two bottles (one on top side of downtube and one below).
8
1X DRIVETRAIN SETUP
Frameset is designed specifically for a single chainring crankset, further maximizing clearance for high-volume rear tire.
9
BOOST TECHNOLOGY
Wider hub spacing (110mm front/148mm rear) results in stiffer wheels for added control plus more tire clearance and an improved chainline for optimal drivetrain performance.
10
GIANT TUBELESS SYSTEM
Integrated Tubeless WheelSystem and tires deliver improved efficiency, comfort and control in the most user-friendly and reliable system.
