A special feature of the Switch Infinity system is that the central pivot point moves up and down by just 5 mm on the two Fox Kashima rods during compression and rebound. This simulates an infinitely long virtual lever as opposed to the predecessor Switch Link with an extremely short lever. The system looks complex, and it is. According to Yeti, the effort is worth it, because Switch Infinity combines very good drive neutrality with optimum suspension performance. Durability should not be a problem.
Practical test of the Yeti Switch Infinity system
Riding a Yeti is and remains emotional. But even from a sober point of view, the brand new Switch Infinity kinematics provide the basis for one of the best rear suspension systems currently available in the all-mountain and enduro sector. The rear suspension subjectively combines a high level of composure when pedalling with very usable suspension travel right down to the last millimetre. Even on the Enduro SB6c, the rider is only tempted to use the platform lever of the Fox shock when pedalling aggressively or on very steep climbs. Instead, the rider constantly enjoys the comfort and traction-giving character of the outstanding rear suspension.
PLUS Optimum spring travel utilisation with high efficiency
PLUS Damper can almost always be driven open
MINUS Special, elaborate frame construction, no space for bottle cages in the frame
Variants of the Yeti Switch Infinity
As the youngest child of the Yeti engineers, Switch Infinity can currently only be found on the two models SB5c (All Mountain with 127 mm travel) and the SB6c (Enduro with 156 mm, pictured above). The bare frame kit for customising the SB5c costs 3390 euros, while a complete SB6c bike with the Sram X01 shown would cost 7190 euros.
