You might think that, given its penchant for model names that are, essentially, serial numbers, Yeti Cycles' Super Bike family would be easily partitioned into specific sub disciplines. The all new SB5. 5 Carbon Mountain Bike Frame would prove you wrong. If rear travel the source of the numbering convention is your chief criterion, then you might think the SB5. 5 is an ambitious trail bike. But the short stays and 29in wheels tell a different story, one that features big watts on long climbs. And then there's the surprisingly compact wheelbase, which lends the SB5. 5 a decidedly non 29er ability to dice techy terrain. So you could twist yourself into rhetorical contortions trying to classify it, or you could just let the bike speak for itself on the trail. We've already seen Yeti impose its Super Bike philosophy on the wagon wheel category with the SB4. 5, but the SB5. 5's additional inch of rear travel rewards the more adventurous rider with a machine that flattens big hits with the same aggression that it cleans long climbs. By more adventurous, we don't mean plodding bikepacking trips with 70lb of gear lashed about your person and frame. We mean aggressive. Not afraid to take the steppier line. Testing bikes on terrain they may or may not be able to handle. Instead of more adventurous, some might write reckless. Whatever. We'll leave those people with their overly restrictive, discipline specific cycling while we take the SB5. 5 across all the ups, downs, ins, and outs of true all mountain riding. Yeti's Switch Infinity suspension is the lynchpin of the SB5. 5's seemingly limitless capabilities. Its linear travel hits the sweet spot of anti squat to keep pedaling sharp across rocky climbs, and it also erases the momentary harshness that its predecessor, the Switch Link design, would display when pushed to the absolute limit. Go ahead and ride the shock open it'll still claw up anything without sacrificing on big hits and deep rollovers. The key d...
