Yeti Cycles SB140 C2 GX Eagle Mountain Bike

The SB140 C2 GX Eagle is a mid-travel ripper that blends playful handling with big-mountain confidence

What Our Gearhead Experts Are Saying:

"The SB140 C2 GX Eagle is the bike I grab when I want to ride anything and everything. The 140mm of Switch Infinity suspension is efficient yet plush, making climbs feel smooth and descents feel bottomless. The Fox Performance 36 tackles chunky terrain with confidence, while the GX Eagle drivetrain delivers precise shifting over the steepest climbs. Whether I´m dropping into technical descents or boosting off trail features, this bike keeps things fun and controlled."

Built to thrive on rough terrain and playful lines, the Yeti SB140 C2 GX Eagle is the ultimate trail machine. Its C-Series carbon frame is engineered for speed and durability, with Yeti´s Switch Infinity suspension offering a buttery smooth 140mm of rear travel.

Paired with a Fox Performance 36 fork and 150mm of front travel, this bike stays composed on big hits while remaining agile for technical sections. The SRAM GX Eagle drivetrain provides crisp shifting across a wide 10-52T cassette, ensuring we can charge up steep climbs and hammer down descents. Crankbrothers Synthesis Enduro wheels wrapped in Maxxis Aggressor tires deliver traction and control, while the SRAM G2 R brakes provide confident stopping power.

From alpine singletrack to rugged enduro trails, the SB140 C2 GX Eagle is designed for riders who want a bike that´s as fast as it is fun.
