The SB140 29 C3 GX AXS Factory is built for riders who want a trail bike that feels composed when the terrain gets steep, technical or unpredictable. At its heart is Yeti’s C Series carbon frame, designed around the proven Switch Infinity suspension system. The refined frame silhouette not only looks purposeful but also increases ground clearance and optimises stiffness across all frame sizes for a consistent ride feel.
With 140mm of rear travel paired to a 160mm FOX Factory 36 fork with GRIP X2 damper, the SB140 is tuned for control on rough descents while remaining supportive under power. The suspension kinematics are designed to offer sensitivity off the top, a stable mid-stroke and controlled progression towards the end of travel, giving confidence when pushing harder on challenging trails.
Geometry is size-specific, placing riders in a balanced, centred position for improved control on steep climbs and descents. The longer reach and considered frame layout encourage confident handling without feeling unwieldy on tighter sections.
Shifting is handled by SRAM’s GX Eagle AXS Transmission, delivering precise, wireless 12-speed performance. The 10–52T cassette provides a wide gear range for steep technical climbs and fast transitions. SRAM Maven Base hydraulic disc brakes offer powerful, consistent stopping control when the trail demands it.
Rolling on 29in DT Swiss M1900 wheels, the SB140 is fitted with a Maxxis Minion DHF 2.5 EXO front tyre and Minion DHR II 2.4 EXO rear, a proven combination for grip and braking traction across varied conditions.
A OneUp dropper post with size-specific travel ensures you can adjust saddle height easily for technical descents and steep roll-ins, while Burgtec finishing kit adds durability and control.
For riders looking to explore deeper into technical terrain or take on long, demanding trail days, the Yeti SB140 29 C3 GX AXS Factory delivers a refined balance of suspension performance, modern geometry and dependable components.
