Yeti Cycles SB120 C2 GX Eagle Mountain Bike

Effortlessly fast and capable, the SB120 C2 GX Eagle Mountain Bike delivers XC efficiency with trail-bike confidence

What Our Gearhead Experts Are Saying:

"The SB120 C2 GX Eagle is a blast to ride. It´s incredibly efficient on climbs, but when the trail turns downhill, the 120mm of Switch Infinity suspension keeps things smooth and composed. The Fox Performance suspension soaks up rough sections, while the SRAM GX Eagle drivetrain offers reliable shifting for long days in the saddle. This bike is the perfect balance between lightweight speed and playful capability."

For riders who want a bike that´s as eager to climb as it is to descend, the Yeti SB120 C2 GX Eagle delivers a perfectly dialed blend of efficiency and capability. With 120mm of Switch Infinity suspension in the rear and a 130mm Fox Performance 34 fork, this bike absorbs bumps and chatter while maintaining the responsiveness needed for quick acceleration.

The C-Series carbon frame offers a stiff, lightweight platform for big trail days, while the SRAM GX Eagle 12-speed drivetrain provides crisp shifting and a wide gear range to tackle steep climbs and fast descents. The DT Swiss M1900 wheels, paired with Maxxis Minion DHF and Aggressor tires, deliver a fast-rolling yet grippy ride, perfect for navigating technical singletrack with ease.

Designed for those who live for all-day adventures and post-ride high-fives, the SB120 balances speed, efficiency, and fun, making every ride feel effortless.
