"Is the SB100 an XC bike that descends like a downhill rig or a trail bike that climbs like a hardtail? The answer is yes - it does not ride like a traditional 100mm bike." - Matt Phillips, Bicycling Editors' Choice
The SB100 is the result of what Yeti can do with short travel and Switch Infinity. It transcends the weight-weenie, uphill only models and replaces it with a precision riding bike. Some people assume it's a downhiller's XC bike but for Yeti, it's simply the bike they always wanted to build.
Discipline: XC | Material: Carbon Fibre | Travel: 100mm
TURQ Series bikes are made with the highest quality carbon fibre available and offer the perfect balance of stiffness and compliance, resulting in 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, Yeti's in-house testing team and ambassadors around the world.

Durability tested by Richie Rude
The SB100 is a strong XC climbing machine, but the gravity inspired geometry, 120mm Fox 34 step-cast fork and meaty tyres are all trail. The result is a perfect blend of pedalling efficiency with downhill prowess. Yeti redesigned the Switch Infinity mechanism specifically for 100mm of travel - it's light, and tucks behind the seat tube so that a water bottle can be accommodated in the front triangle. Big days require big bottles. Instead of chasing feather weight on the build, Yeti spec'd the bike as they tested it with a Fox Transfer post, Maxxis 2.3 tyres, and 180mm front rotor. It's still light, but also right. Yeti's Pro rider, Geoff Kabush, will be defending his BC bike race title on this rig and it will also be his sled of choice for Downieville and The Breck Epic.
Yeti aimed to strike a balance between durability, weight and price when they spec'd the SB100 TURQ Series X01 Eagle. Like all the other SB100 models they made sure this trail bike was ready to rip with beefy Maxxis tyres and SRAM's new carbon X01 DUB™ crankset system. For all turq models, Yeti spec Fox's new Factory Step-Cast 34 Fork, this lightest in its class. Strong Shimano XT brakes are also hung on this bike with 180mm front and 160mm rear rotors.
PURPOSE BUILT
Re-Designed Switch Infinity
The Switch Infinity was re-designed specifically for 100mm of travel. It is lighter and tucks neatly behind the seattube. There is no performance difference between this and the other switch mechanism. The SB100 switch utilises the same proven FOX Racing bushings, seals, and Kashima stanchions as the Switch found on other models.
No More Gunk on your Bottle
The water bottle fits comfortably inside the front triangle, where you might be used to having it. It took considerable effort to accommodate a bottle, optimise stand-over and meet Yeti's kinematic expectations.
Uninterrupted Seattube
The new Switch Infinity design and placement is visually pleasing creating classic frame lines whilst the uninterrupted seattube allows space for longer dropper seatposts.
Genre Killing Geometry
Inspired by going fast downhill but balanced to provide uphill efficiency. The SB100 blurs the lines between XC and Trail. A longer front centre with shorter chainstays and a slacker head angle find the right combination of up and down. The design also allows for an uniterrupted seatpost, to fit a longer dropper.
Integrated Headset
The SB100 employs an integrated headset and cleaner carbon layup, meaning there are no aluminium inserts and less material in the headset juncture, resulting in a lighter, stronger front triangle.
Internal Routing
Internally tunneled cable routing allows for clean lines and a quiet rattle-free ride. It also makes servicing your bike easier.
TECHNOLOGY - Experience the Yeti Difference
Switch Infinity
Is a Yeti patented system that utilises a linear translating pivot, providing a tailored anti-squat curve that other systems cannot physically achieve. 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.
Tunable
Switch Infinity is a versatile system easily adaptable to different travel platforms. It can be mounted in any orientation and can achieve a myriad of kinematics depending on the design intent. For explample, longer travel bikes require drastically different kinematics later in the travel (controlling wheel path trajectory). The Switch Infinity system can control this much more precisely than other suspension designs because of the linear path of the main pivot. It also means the leverage ratio and anti-squat can be controlled with much greater freedom than other systems.
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. Only the best components are used in its construction - Kashima coated stanchions for low friction and durability, seals and bushings that are used in FOX's off-road racing division, and a lightweight forged translating pivot.
Anti-Squat
Yeti are aiming for a relatively flat and high anti-squat curve in the beginning and mid-section of travel where pedaling commonly occurs, i.e. the pedaling zone. This creates an efficient pedaling platform through the entire pedaling zone, as opposed to one single point. After the pedaling zone, there is an inflection point where the Switch Infinity link begins to move down, dropping the anti-squat drastically. You're typically not pedaling in this zone so you need the chain forces to have less of an effect on the suspension performance since it's an opposing force.Decoupling of the chain forces allows the suspension to work more efficiently to absorb impacts.
Leverage Ratio
Yeti aim to deliver a leverage rate with linear progression. A straighter, more linear curve means it's easier to tune shocks to pair with the suspension kinematics, and you don't have to rely on damping circuits to compensate. You can choose a leverage ratio that provides small bump sensitivity and enough progression to maintain mid-stroke support and bottom out control. Being able to manipulate the leverage ratio without affecting the anti-squat characteristics is unique to Yeti's patented Switch Infinity suspension.
