2026 Yeti SB140 C3 GX AXS Transmission Mountain Bike
The 2026 Yeti SB140 C3 GX AXS Transmission is a high-performance trail and enduro bike designed for riders who demand modern geometry, efficient pedaling, and confidence-inspiring suspension. Its C/Series carbon frame is paired with Performance Switch Infinity V2 suspension to deliver outstanding traction, mid-stroke support, and climbing efficiency.
Up front, the 160mm Fox Performance 36 fork works in harmony with the 140mm Fox Performance Float X rear shock to smooth out rough terrain while maintaining stability at speed. This suspension setup makes the SB140 equally capable on technical climbs and aggressive descents.
The bike is equipped with a SRAM GX Eagle AXS Transmission drivetrain for precise, wireless shifting under load, while SRAM Maven hydraulic disc brakes deliver consistent and powerful stopping performance. DT Swiss M1900 wheels paired with Maxxis Minion tires provide durability, traction, and confidence across demanding trail conditions.
