The 2025 Yeti SB140 C2 GX is built for riders who want a trail bike that handles everything from punchy climbs to fast, technical descents with confidence. The heart of this bike is its C Series carbon frame, which balances lightweight strength with durability. The frame’s progressive geometry includes a slack head angle and longer reach, which means it stays stable when you're bombing downhill but stays agile when the trail gets tight.

Yeti’s Switch Infinity suspension system is a standout here. It provides a plush ride without feeling sluggish when you pedal. Internal cable routing keeps things tidy and protected from the weather. Plus, the threaded bottom bracket makes maintenance straightforward.

The drivetrain is SRAM GX Eagle, a 12-speed setup with a wide 10-52T cassette that lets you climb steep sections without spinning out and hit flats with speed. The single chainring setup keeps things simple and light while delivering smooth, reliable shifts.

You'll also find a set of SRAM G2 R brakes paired with Centerline rotors (200mm front, 180mm rear). These brakes offer strong modulation and confidence-inspiring control even on long, steep descents where precision matters.

The suspension is handled by Fox Performance components. Up front, the 36 fork offers 150mm of travel with the stiffness and small bump sensitivity needed for aggressive riding. Out back, the Float DPS shock has 140mm of travel and three compression settings. You can dial in your ride from open to firm depending on the trail and your style.

The wheels and tires combo suits the bike’s aggressive nature. DT Swiss M1900 30mm rims balance weight and strength, while Maxxis Minions provide grip and durability. The DHF 2.5 Exo up front digs into loose and rocky terrain, and the Aggressor 2.3 Exo out back rolls fast while maintaining cornering control.

A OneUp 31.6 dropper post lets you quickly adjust your saddle height on the fly. This is key for maintaining balance and control from climbs to hairy descents.

Up front, the cockpit is made by Burgtec, with a wide 780mm alloy handlebar that gives great leverage and stability and a 50mm stem for responsive steering. The Cane Creek 40 headset keeps things smooth and reliable over time.

Underneath, the SRAM Dub BSA 73 threaded bottom bracket ensures solid power transfer without the creaks that sometimes plague press-fit systems.

Performance on the trail

• Climbing feels efficient thanks to the Switch Infinity suspension and wide gear range.
• Descending is confident with ample suspension travel, powerful brakes, and grippy tires.
• Technical sections feel manageable thanks to wide bars, balanced geometry, and a responsive suspension platform.

The 2025 Yeti SB140 C2 GX suits riders who want a reliable, high-performance bike ready for aggressive rides and complex terrain.
