It's Time To Re-calibrate Your Gray Matter With What's Happening In Racing Today. All It Takes Is "It's On!" - Number Plates Not Required. Born To Naturally Crush The Climbs, The SB115 Is Evolved. Deft On The Downs. Designed To Race. Built To Rally.


  • A lighter Switch

    Short-travel specific design of Switch Infinity, turned 90 degrees and optimized for lighter weight and efficiency.

  • More than added travel

    Crushing souls on the descent is more than half the fun. And a hell of a lot more than half the point. The SB115 has 115 genre killing millimeters of travel, that work harder than ever before.


    Across our line, we have chosen a relatively flat and high anti-squat curve in beginning and mid-section of travel where pedaling commonly occurs a.k.a the pedaling zone. This creates an efficient pedaling platform through your entire pedaling zone, there is an inflection point where the Switch Infinity link moves down, dropping the anti-squat drastically. Riders are typically not pedaling in this zone, so chain forces have less of an effect on the suspension performance. Decoupling of the chain forces allows the suspension to work more efficiently to absorb impacts making the feel of a Yeti distinct.

  • Deft On The Downs Designed To Race Built To Rally
  • XC is no longer a glorified gravel race.
  • I've had to remind myself I'm not riding a SB130 - Joey Schusler


    Efficient, capable, direct.

  • Blanco or hot fire? You decide.

  • Longer-travel setup. No Downside.

    We custom tune the shock on every Yeti to compliment Switch Infinity's unique characteristics. Unlike other "short-travel" trail bikes the SB115's suspension performs best even when set up with sag numbers (30%) akin to much longer travel bikes. We don't leave it to someone else to make every millimeter of the SB115's suspension travel count.

  • Multi-stage, multi-day, more involved, higher-speed, the SB115 excels in new-school trans-XC style racing and riding.

  • 1. Forward BIAS Posture

    Gives racers room to stay comfortable over long race days.

    2. AN "Appropriate" Frame Reach

    Keeping racers agile, able to react to race tactics, and tightly taped courses.

    3. A Low BB

    For that “in bike feeling” on the ascent or pushing hard on the way down.

    4. 130mm Fork

    Because our 115mm of rear suspension outperforms similarly stroked forks and pairs well with our more forward biased geometry.


At the heart of the SB115 suspension design is our patented Switch Infinity suspension system. Switch Infinity utilizes a patented translating pivot that switches direction as the bike moves through its travel providing excellent anti-squat characteristics.

  • Switch Infinity 01: Pivot Translation

    Switch Infinity utilizes a patented translating pivot that switches direction as the bike moves through its travel. This provides a tailored anti-squat curve while allowing the leverage ratio to be tuned independently, something other systems can’t physically achieve.

  • Switch Infinity 02: Bottomless Feel

    An initially high anti-squat value delivers superior pedaling performance. Further, into the travel, the anti-squat quickly drops off to allow the custom-tuned FOX Racing shock to perform as intended. These characteristics provide excellent mid-stroke support and a bottomless feel.

  • Switch Infinity 03: Tunable

    Switch Infinity is a versatile system easily adaptable to different travel platforms. The system can be mounted in any orientation and can achieve a myriad of kinematics depending on the design intent. The Switch Infinity system can control this much more precisely than other suspension designs because of the linear path of the main pivot.

  • Switch Infinity 03: Durable

    The Switch Infinity is a simple, lightweight, bombproof system built by FOX Racing Shox from proven suspension components and engineered and tested to withstand the worst riding conditions. We use seals and bushings that are used in FOX's off-road racing division and a lightweight forged translation pivot.


Made with the highest quality carbon fiber available, TURQ series bikes offer the perfect balance of stiffness and compliance.

  • Materials 01: TURQ Series

    TURQ Series bikes are made with the highest quality carbon fiber available and offer the perfect balance of stiffness and compliance. The result is a bike that feels smooth, solid and aggressive. Every bike is tested by the best racers in the world, including EWS World Champion Richie Rude, our in-house testing team and ambassadors around the world.

  • Materials 02: C/ Series

    By making small changes in the carbon fiber layup of our TURQ Series bikes, we are able to create a more aggressively priced carbon high-performance mountain bike. C-Series frames maintain the strength and stiffness of the TURQ Series. The carbon fiber in C-Series weighs a bit more, about 225g per frame. Every bike model is offered in at least one C-Series option with high-end components.

  • Materials 03: 225 Grams Lighter
    • Highest Quality Carbon Fiber Available
    • Perfect Balance Of Stiffness &Amp; Compliance
    • Optimized Layup Reduces Weight
    • Durability Tested By Richie "F-Ing" Rude

Lifetime Warranty

The SB115 frame and Switch Infinity link are covered by a Lifetime Warranty. You can race, jump, ford streams, shred the gnar or ride it hard. Don't worry, you don't need a lawyer to decipher how it works.
