Yeti SB120 C2 90 Bike 2026Short Travel. Zero Compromises. The sweet spot between XC efficiency and trail capability has always been a moving target. The SB120 lands on it perfectly. The C-Series carbon frame runs the Switch Infinity V2 suspension, Yeti's translating-pivot design that migrates its main pivot through the stroke to maintain pedaling efficiency early in the travel and then back off the anti-squat deeper down where you need suppleness the most. The result is 120mm of rear travel that rides bigger than the numbers suggest and climbs cleaner than anything with this much compliance has the right to. A 66. 5-degree head tube angle and a steep 76. 5-degree effective seat tube angle keep you over the front on climbs and in an aggressive position when the terrain changes Size-specific chainstay lengths and a proportional geometry approach mean the bike is dialed from XS through XXL, not just scaled up from a medium. The C2 90 build pairs the carbon frame with a SRAM Eagle 90 T-Type Transmission drivetrain, a 10-52T cassette, and a 30T chainring for a gear range that covers everything from grunt-mode climbs to fast singletrack. SRAM Motive Bronze hydraulic disc brakes handle stopping duties front and rear. DT Swiss M1900 30mm inner-width rims come laced and ready to run tubeless, wearing Maxxis Minion DHF up front and Aggressor out back. The Fox FLOAT DPS Performance rear shock feeds into a Fox FLOAT 34 Performance fork with 130mm of travel up front, keeping the front end composed on technical terrain. A Fox Transfer dropper post rounds out a build that gives you the tools to ride this bike to its full capability from the first punchy climb onward.
