Yeti SB 4.5
The SB4.5 is like the quiet bike that doesn’t really boast, but when called upon to perform, it does so in heroic fashion. The 4.5 is so versatile and fast that it should be on everyone’s short list for a one-bike quiver. This bike pedals like a rocket, but never shies away from tough, technical lines. This is a fast and capable trail bike - period.

Not sure which bike to get? Get this one. Similarly capable to the ever-popular SB5, but with a slightly different character. This bike loves to be pedalled hard, and responds beautifully to rider input. The handling is sharp, but not overly quick. It’s maneuverable but not hyperactive, efficient, but not harsh. The 4.5 may be a little less rowdy than the 5, but only due to the tendency of 29” wheels to draw slightly straighter lines. This bike is playful enough, but happy to stay planted on the ground. The spec on the X01 build is great - but this bike could do well with a lighter build, or a beefier build depending on rider preference. We love this bike!
