"Race Bred" It's Not Just A Slogan Printed On The SB150 Top Tube. We've Been Pinning On Numbers And Pinning The Throttle Since 1985.


  • Feels Fast, and is Fast are different

    Line corrector, time saver, full travel user: tuning. Switch Infinity to go faster while pedaling or not.

    An inflection point for speed

    We took Switch Infinity’s winning heritage and made the leverage ratio more progressive (but not too progressive) to provide greater compatibility with modern shocks and a wider range of racer setups. In addition, the bike has better small bump compliance, ramps up quicker in the mid-stroke, while still allowing for full travel and bottom-out control. Racers spend more time in the supportive part of the curve - when entering toothy sections or carrying corner speed, the SB150 offers something to push against for greater race stage velocities.

    Inflection Point: 81 mm

    At the inflection point, anti-squat forces on the suspension drop, to allow for the suspension to perform independent of pedaling forces.

  • Leverage Rate

    Our relatively linear progression curve ensures racers get more track speed, and full travel from their suspension. Forget what you know  the clock proves more progressive curves aren’t faster.

    For some, generating and maintaining speed is an elusive pursuit. When racing against the clock, our curve keeps racers skipping across the top of obstacles with the confidence of knowing there’s more travel available, should they need it. A straighter, more linear progression curve means it’s easier to tune shocks to pair with the suspension kinematics, and we don't have to rely on damping circuits to compensate. Being able to manipulate the leverage rate without affecting the anti-squat characteristics is unique to our patented Switch Infinity suspension.

    Progressivity 15%

    Get more out of the suspension travel that’s efficient for race applications. Have the ability to tune it to hold more speed as racers hone their craft.

  • Tunable for Stage Decimating Performance

    Richie Rude wins running the same suspension design that comes stock on the SB150. No team only linkage or mods to his Switch Infinity. As personal performance elevates, racers are able to tune the SB150 to carry more and more speed – right up to the top of the box.

  • The faster I go, the more alive it becomes.


    Capable, stable, efficient, astonishingly fast.

  • Anti-Squat

    Across our line, we have chosen a relatively flat and high anti-squat curve in the 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, as opposed to one single point. After the 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 suspensions performance. Decoupling of the chain forces allows the suspension to work more efficiently to absorb impacts making the feel of a Yeti distinct.

  • Progressive Race Driven Geometry

    Designed for shorter fork offsets, the SB150’s headtube angle is slackened and the seat tube angle is way steeper. The reach is also longer with shorter chainstays. Advantage? All of these elements increase the DH prowess and move the rider forward on the bike. But these advantages are not one-sided. The steeper seat angle, short fork offset, and forward riding position also keeps the front wheel on the ground, the power to the pedals and the steering quick and nimble when climbing.

  • 1. Forward BIAS Posture

    Gives racers the room they need, and centers them on the bike.

    2. 20mm Longer Travel Fork

    Pairs well with our forward-biased frame matching the vertical wheel travel of the rear suspension.

    3. Slacker Headtube

    Lower bottom bracket, and longer wheelbase.

    4. Teasted to DH Standards

    High-impact strength, carbon lay-up tuned to go fast and tested to DH standards.

  • Through timed testing, we proved the resulting ride characteristic helped racers carry higher downhill race speeds.

  • Wishbone Shock Extender

    Our patent pending wishbone shock extender changes leverage ratio, maintains kinematics and maximizes stand over clearance. For racers, the shock can be removed from the frame under two minutes to change a shock tune or perform a race day service.

  • Custom Shock Tune

    Each Yeti model has a custom shock tune that is developed in house. Each tune is specifically designed to work in conjunction with the leverage ratio and anti-squat performance properties the engineering team builds with each frame. The performance characteristics of the SB150 are built using qualitative data from our athletes, and quantitative data recorded from telemetry devices which allow us to derive a tune that both enhances mid-stroke and bottom-out control while maintaining its pedaling efficiency.


At The Heart Of The SB150 Suspension Design Is Our Patented Switch Infinity, With A Translating Pivot System For 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 SB150 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.
