The SB5.5c is where the trail, all-mountain and gravity bike intersect. Tried and tested under the likes of EWS champion Richie Rude and our in-house test team, this lightweight bike eats up grueling technical climbs and hauls going downhill. Forget any preconceived notions about 29ers, thanks to an impeccable frame design, shortened chain stays and aggressive suspension spec, this bike is easy to maneuver and feels lively and quick on the descents.

Yeti's patented new Switch Infinity design allows their engineers to control suspension kinematics to a new level. The end result is unprecedented pedaling efficiency and small bump sensitivity when climbing paired with plush, controlled travel when descending. The Switch Infinity technology was created in partnership with FOX and features Kashima coated stanchions and FOX’s renowned build quality. It has endured Yeti and FOX's rigorous testing protocol and over three years of on-trail testing. The system is simple, lightweight and low-maintenance.

Utilising the new patented Switch Infinity Translating Pivot that ‘switches’ direction as the bike moves through its travel Yeti are able to control the bikes 6” of suspension perfectly throughout its entire suspension stroke. This results in confidence inspiring performance and amazing trail feel. As the bike starts to cycle through its travel the main pivot translates upwards along two Kashima coated shafts to create a rearward axle path. This movement gives excellent anti-squat and optimum pedalling performance while maintaining a crisp pedal stroke. Housed on a sliding carrier the pivot then ‘Switches’ direction as the bike continues through its travel and the Switch Infinity link translates downwards to give a bottomless feel and stop any chain force adversely affecting the suspension performance out on the trail.

The evolution of Yeti’s Switch Link Technology is a relatively simple one as Switch Infinity offers a lighter, stronger system engineered by FOX from proven suspension components designed and tested to withstand the worst riding conditions. Kashima coated stanchions offer low friction and durability while the seals and bushings are borrowed from FOX’s off-road racing division. After months of trail and dyno testing in all conditions the system has been found to be worthy enough to be “Enabled by FOX” sealing its high performance and quality.
