2026 Yeti SB120 C3 GX AXS Transmission Mountain Bike
The 2026 Yeti SB120 C3 GX AXS Transmission is a modern carbon trail bike designed to deliver efficiency, precision, and confidence across a wide range of terrain. Built on Yeti’s refined C/Series carbon frame with Performance Switch Infinity V2 suspension technology, the SB120 balances pedaling efficiency with exceptional traction and control.
A Fox Performance 36 SL fork with 140mm of travel paired with a Fox Performance Float rear shock (120mm) ensures smooth handling on technical climbs and aggressive descents. Internally tunneled cable routing, sealed Enduro Max pivot bearings, and UDH compatibility make the frame durable, clean, and future-proof.
Shifting is handled by the SRAM GX Eagle AXS Transmission, a wireless T-Type drivetrain that delivers crisp, reliable performance under load. Powerful SRAM Motive Bronze hydraulic disc brakes provide consistent stopping power, while DT Swiss M1900 wheels with Maxxis Minion DHF and Aggressor tires keep traction predictable on demanding trails.
