The dust around the Great Wheel Size Debate has settled with 29ers dominating nearly every category of mountain biking. But there are some things inherent to wheel size that 29ers simply can’t do.
There’s main lines and race lines. And then there’s the completely unexpected lines that requires a rider with a different headspace all together.
27.5-inch wheels handle effortlessly, are more precise, accelerate quicker, and corner with ease. They pop and play, they dodge and weave. If big wheel bikes are the math nerds calculating maximum speed and efficiency, then 27.5” bikes are the art students painting, exploring, and expressing their way through the trails.
The SB135 is for riders who factor their rides in fun over feet gained, who rate their rides on quality, not quantity. For riders who measure the immeasurable.
Yeti’s goal with the SB135 was to employ the feature and technology updates that debuted on the SB120, SB140 and SB160 last fall, to make the most agile trail bike we could. We experimented with different wheel size combinations and dual 27.5-inch wheels gave us the fun-factor we were after with this bike.
Dual 27.5-inch wheels are also ideal when creating the best fit for smaller riders. This was one of the chief design goals of the SB135. The engineering team actually went so far as designing a totally different frame for the small and XS sizes that minimizes standover height, maximizes dropper post travel, and allows for a water bottle inside the frame.
Throw out your preconceptions and throw a leg over the SB135. The small-wheel revival starts now.
