2025 Yeti SB140 LR C3 GX Transmission

The 2025 Yeti SB140 Lunch Ride C3 GX Transmission is built tough for riders who want a bike that handles everything from steep climbs to fast descentswith ease. Central to this bike is the C Series carbon frame, which balances being lightweight with the strength needed to take on rough trails. The frame’s geometry is designed to give you confidence, with a slack head tube angle and short chainstays that make turning tight corners easier while still feeling stable on big downhills. Yeti’s Switch Infinity suspension sits right in the frame, so pedaling stays efficient while the suspension smooths out bumps and rocks. No loose cables here. Everything routes cleanly inside the frame, and the threaded bottom bracket means less hassle when it’s time to service.

Wireless shifting system

Shift gears without pulling a cable. that's what SRAM’s GX Eagle AXS wireless transmission offers. A 12-speed cassette ranges from 10 to 52 teeth, giving you plenty of options whether you’re grinding uphill or speeding down. The wireless setup keeps the cockpit tidy and makes shifting quick and precise. There are no wires to snag and less chance of something breaking on the trail.

Brake system

You'll also find a set of SRAM Code R brakes paired with Centerline rotors (200mm front, 180mm rear). These brakes are designed to give solid, consistent control whether you’re easing into a sharp corner or hammering a steep descent. They manage heat well, so you won’t lose bite when things get technical or the ride gets long.

Suspension details

The suspension front and rear comes from Fox’s Performance line. Up front, the 36 fork offers 160mm of plush travel with solid damping to soak up big hits and keep you on line. The 140mm Float X shock keeps the rear end lively and predictable. It's fine-tuned to mesh perfectly with the Switch Infinity system. That combo strikes a balance that keeps climbing efficient but lets you pick up speed when the trail drops away.

Wheels and tires

Wheels are DT Swiss M1900 rims with a 30mm internal width, tough enough for aggressive riding but light enough to stay nimble. Tires are Maxxis Minions front and rear. The DHF 2.5 EXO up front grips loose and rocky ground with ease. The DHR II 2.4 EXO in back rolls fast while providing excellent braking and cornering traction. They're a tried and tested combo that simply works on most trail surfaces.

Dropper post

The OneUp dropper post lets you switch saddle height quickly while riding, offering more control on technical climbing and better positioning for descents. Smooth, solid, and reliable, what's a small part that makes a big difference.

Handlebars and stem

Your hands sit on a wide 780mm Burgtec Ride Wide handlebar, paired with a 50mm Enduro MK3 stem. This cockpit setup gives you plenty of leverage and precise steering feedback without sacrificing comfort. This is especially useful when navigating tricky sections or riding fast.

Headset and bottom bracket

Turning the bars feels smooth thanks to the Cane Creek 40 integrated headset, known for lasting bearings and precise steering. The bottom bracket uses SRAM’s Dub BSA 73 threaded design, combining stiffness with ease of maintenance and excellent power transfer.

Trail performance

How does this all come together on the trail? Climbing feels efficient thanks to the lightweight frame, smooth suspension, and the broad gear range of the GX Eagle AXS. Descending is confident and stable, with plenty of suspension travel and grippy tires to keep you planted. Technical sections do not slow you down either. The bike’s geometry, brakes, and wide bars make tight corners and rocky trails manageable and even fun.

Summary

In short, the 2025 Yeti SB140 Lunch Ride C3 GX Transmission is a bike ready to tackle a wide variety of trail challenges. Its mix of modern tech, solid components, and smart design means fewer compromises whether you want to climb, descend, or just explore.
