2018 Yeti SB5+ Carbon Shimano XT/SLX
The SB5+ is its own beast. Built on a 27.5 plus platform, it can accomodate up to 3.0 tires. This isn’t the SB5 with plus tires on it – it’s a plus-sized dedicated bike that takes on loose gravel and varied trail conditions with ease.
The spec level on the SB5+ Carbon Shimano XT/SLX is all about gear ratio and harnessing traction and stability, while optimizing playfulness. Fox Performance suspension with 150mm in the front and Transfer seat post make this bike agile and maneuverable when you need it most. Maxxis Rekon 2.8 tires round out this traction focused build.
There are no flip-chips here to change the bike’s geometry, no multiple wheel sizes, nothing to alter Yeti’s suspension kinematics. Yeti discovered that slight changes in tire diameter had a dramatic impact on critical frame properties such as bottom bracket height and mechanical trail. Not wating to sacrifice any defining ride characteristics by adopting the wheels to fit an existing platform, the SB5+ was born into its own identity in the Yeti line.
By making small changes in the carbon fiber layup of their TURQ Series bikes, Yeti was able to make a more aggressively priced carbon high-performance mountain bike while maintaining strength and stiffness of its higher end sibling. The carbon fiber weighs a bit more, about 250 g for a frame. You’ll see that every bike model is now offered in carbon with high-end components.
