Brand: Yeti
THE SB5C IS OUR INTERPRETATION OF WHAT A TRAIL BIKE SHOULD BE - LIGHTWEIGHT, GREAT PEDALING UPHILL AND A SCREAMER GOING DOWN. THIS BIKE WILL MAKE YOU SMILE.

We've taken all we've learned from our popular Switch Technology and merged it with our bump smashing 303 Rail Technology to come up with a completely new suspension design called Switch Infinity.

This new system allows the suspension to achieve seemingly contradictory characteristics. In the early stage of the travel it displays superior pedaling efficiency and excellent small bump sensitivity. As you move deeper into the travel, it is well supported and responds effortlessly to square edge hits.

What does that mean from a rider's perspective? You can hammer away in all conditions, including rough, chunky ascents with zero loss in efficiency. You don't get knocked off-line, and you have amazing traction. Point it down and it's very fast. The controlled mid-stroke keeps the bike composed through rough terrain and g-outs, while allowing it to open up when encountering bigger hits deeper in the travel.

Our geometry has always been progressive and mirrors our gravity-influenced riding style - long top tube, low bottom bracket, and slack head angle. This allows the bike to achieve great front to rear balance when descending. When pounding the pedals uphill, you'll appreciate the seat tube has been moved forward a bit to put the rider in the optimum pedaling position. It feels right from the moment you get on it.

And here's the bell ringer - the frame weighs just 5.1 pounds and is very stiff, so you can hold your line no matter how hard you push.

Switch Infinity Suspension:
Overview

Switch Infinity utilizes a patented translating pivot that switches direction as the bike moves through its travel. This provides excellent anti-squat characteristics for superior pedaling performance and ideal suspension characteristics as it gets deeper into the travel.

Efficiency

At the beginning of the travel, the main pivot translates upward, creating a rearward wheel path. This provides excellent anti-squat and optimum pedaling performance. While the pedaling is crisp, the linear leverage ratio and translating pivot combine for amazing small bump sensitivity. The linear movement provides unprecedented control of the kinematics and marks a significant improvement over link-based designs.

Control

Once the Switch Infinity system reaches the inflection point, the main pivot begins to translate downward. This linear movement prevents the chain force from adversely affecting the suspension performance and gives the suspension a controlled, bottomless feel.

Mechanical Superiority

The linear path of the patented Switch Infinity system has very little resistance as it moves through its travel. This allows the system to achieve seemingly contradictory characteristics. In the early stage of the travel it displays superior pedaling efficiency and excellent small bump sensitivity. As you move deeper into the travel, it is well supported and responds effortlessly to square edge hits. The mechanical advantage of our linear system cannot be achieved with traditional link designs.

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 only use the best components 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. We have field tested the parts for over three years and the original bushings, seals, and stanchions are still in perfect working condition. Fox has thrown the system into its testing regimen as well - spray testing, mud, dyno, and ride testing - and found the system worthy enough to be "Enabled by Fox." The system is significantly lighter (100g) than the original Switch Technology.

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. For example, 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. We also can control leverage ratio and anti-squat with much greater freedom than other systems.
