If you're an adventurer more than a racer, and want a hardtail mountain bike that's up for it, the Fathom 29 2 is ready.

The Fathom 29 2 is built around a light ALUXX-SL aluminum frame, ensuring excellent handling, climbing and pedaling response. A tapered OverDrive head tube adds a precise feel in tight and twisty singletrack, while a press-fit bottom bracket ensures flex-free power delivery. The slack 66 degree head tube angle makes every technical descent less tricky. Internal cable routing adds a clean look, too. With an air-adjustable Crest RCL suspension fork, the Fathom 29 2 can tackle rock gardens and technical terrain with confidence. The Crest RCL's 130mm of suspension travel handles rough rock gardens and stair-step descents much better than a short-travel XC fork. A 10-speed Shimano shifter operates a clutch-equipped Shimano Deore rear derailleur, adding fingertip precision to every gear change on the Fathom 29 2. Tektro supplies the hydraulic disc brakes and meaty 180mm rotors, adding excellent stopping power even in wet and muddy conditions. 30mm wide alloy 29'er wheels are shod with tubeless 29x2.5" Maxxis tires, boasting considerable grip over gravel, dirt and mud. A Giant Contact Switch dropper post gets the Romero saddle out of the way on steep "tip-ins" with a handlebar-mounted remote lever. Alloy Contact handlebars and stem complete this trail-ready machine for the riders who have no finish line.
