2025 Yeti SB140 LR T3 X0 Transmission

The 2025 Yeti SB140 LR T3 X0 Transmission is built for riders who want a trail bike that performswith ease. If you’re tackling rough climbs, steep descents, or techy terrain, this bike is made to keep up and keep you in control.

The SB140 LR is built with Yeti’s TURQ carbon frame. It strikes a balance between being light and stiff, so pedaling feels efficient but the ride doesn’t get harsh. TURQ Series frames are Yeti's best frame option. They're made with the highest-quality carbon fiber, and designed for the perfect balance of stiffness and compliance. They're built to handle aggressive riding while remaining solid and smooth, and are tested by some of the best racers in the world to ensure they're up to spec.

Yeti’s Switch Infinity suspension sits inside the frame, making pedaling smooth and absorbing trail chatter. Geometry leans toward stability with a slack head angle and a long reach. The short chainstays keep the handling quick when the trail tightens up. The frame also looks clean and modern with internal cable routing.

The drivetrain here is SRAM’s X0 Eagle AXS Transmission. Wireless and electronic, it shifts instantly with a simple button press. The 30T crank paired with a wide 10-52 tooth cassette covers steep climbs and fast accelerations without missing a beat. The Flattop chain adds strength and smoothness. You also get fewer maintenance headaches because there are no cables or wires cluttering things up.

You'll also find a set of SRAM Code RSC brakes, known for strong, consistent performance. The front uses a 200mm rotor while the rear gets a 180mm rotor. Both help keep your speed in check on long downhill runs by shedding heat well.

The suspension includes a Fox Factory 36 Grip X2 fork with 160mm of travel up front and a Fox Factory Float X shock out back offering 140mm. Both are tuned for trail and enduro riding with plenty of adjustability so you can dial in how the bike feels depending on the trail conditions. The Kashima coating on the fork helps everything move smoothly and last longer.

Rolling on DT Swiss XM1700 wheels with 30mm internal rim width, this setup supports wide tires for better grip and cornering confidence. Maxxis tires pair up front with the aggressive DHF 2.5 Exo for traction in loose and wet spots, and the rear gets a DHR II 2.4 Exo for rolling speed, braking control, and versatility.

Adjust your position easily with the Fox Transfer dropper post, which comes in different travel lengths depending on frame size: 150mm for small, 175mm for medium, and 200mm for large to XXL. This lets you move between climbing and descending positions naturally.

The cockpit keeps things comfortable and precise with a Yeti carbon handlebar (35mm clamp, 780mm width) and a Burgtec Enduro MK3 stem (35mm clamp, 50mm length). This gives you solid control and great feedback, even after long rides. The Cane Creek 40 integrated headset keeps steering smooth and reliable.

At the bottom, the SRAM Dub BSA 73 threaded bottom bracket combines stiffness and durability, making sure the crankset transfers your effort efficiently without creaks or flex.

When it’s time to push your limits on the trail, from steep climbs to rough descents, the SB140 LR T3 X0 makes handling technical sections feel natural. This bike is a great all-rounder for riding a wide variety of trails with solid performance.
