Yeti SB6C Switch Infinity Frame

"The SB6C was built as a pure enduro machine and proved its mettle before it went into production, winning two consecutive rounds of the Enduro World Series." - Yeti Cycles

For 2016 Yeti pulled out all the stops re-designing the SB6c to comply with all the latest standards. An upgrade to 148mm boost rear end incorporating Shimano’s new E-thru I-type QR axle. To keep things neat and tidy the whole bike has been given internal routing for the rear brake, derailleur and dropper posts. Through all this tweaking and tuning, the tried and true geometry of the SB6c has been preserved to maintain its podium worthy performance, but now with added extras.


Utilising the 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.
