2026 Yeti SB120 C2 90 Transmission Mountain Bike
The 2026 Yeti SB120 C2 90 Transmission is a modern trail mountain bike engineered for riders who want efficiency, control, and confidence on a wide range of terrain. Built around Yeti’s proven C/Series carbon fiber frame and iconic Switch Infinity suspension technology, the SB120 delivers exceptional pedaling efficiency with impressive traction and composure on technical trails.
With 140mm of front travel from the Fox Performance 36 SL fork and 120mm of rear travel via the Fox Performance FLOAT shock, the SB120 strikes the perfect balance between climbing performance and descending capability. Thoughtful frame details include a threaded bottom bracket, internally tunneled cable routing, sealed Enduro Max pivot bearings, and UDH compatibility for future drivetrain options.
The bike is equipped with the new SRAM Eagle 90 Transmission, delivering smooth, durable, and precise shifting under load. SRAM Motive Bronze hydraulic disc brakes provide reliable stopping power, while DT Swiss M1900 wheels wrapped in Maxxis Minion DHF and Aggressor tires ensure confident traction on aggressive trail rides.
