Are you ready to rip up those trails and get your adrenaline pumping? The Fathom 1 hardtail bike is here to give you your daily dose of singletrack excitement!

Let's start with the lightweight frame. You won't even feel like you're carrying a bike around, making those uphill climbs a breeze. And with 130mm suspension fork, those pesky rocks and bumps won't stand a chance against your smooth ride.

Now onto the real fun stuff - those 27.5 wheels with high-volume tires! You'll feel like you're flying as you hit top speeds and shred through those turns with ease. And with loads of traction, you can take on any terrain that comes your way.

Overall, the Fathom 1 is the perfect bike for any thrill-seeker looking to tackle some serious trails. Get ready to experience a whole new level of speed, control, and fun on your next ride.

Trail tuned design

Balanced geometry with a 75-degree seattube angle puts the rider in a powerful pedaling position on 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.
