Though almost every other model in Yeti Cycles' Super Bike line falls into a very specific use category, our admittedly limited time aboard the brand new SB5. 5 Carbon X01 Complete Mountain Bike has left us stumped. If you judge based on travel alone, surely the SB5. 5 is an aggressive trail and enduro sled. 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.

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.

Testing bikes on terrain they may or may not be able to handle. Instead of more adventurous, some might write reckless. Whatever.

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. Like the rest of Yeti's Super Bi...
