The 2018 Yeti SB5.5 SRAM X01 Eagle is where the trail, all-mountain and gravity bike intersect. This lightweight bike eats up grueling technical climbs and hauls going downhill. Forget any preconceived notions about 29ers — thanks to an impeccable frame design, shortened chain stays and aggressive suspension spec, the SB5.5 is easy to maneuver and feels lively and quick. Their carbon frames are made from the highest quality carbon fiber available and offer the perfect balance of stiffness and compliance. The result is a bike that feels smooth, solid and aggressive. Yeti’s Switch Infinity suspension platform grants you the trail-ruling trinity of deep travel support, small bump sensitivity, and solid climbing. To keep the bike balanced, Yeti used a 160mm-travel fork with 51mm offset combined with a 66.5-degree head angle. Outfitted with SRAM’s 12-speed X01 Eagle drivetrain.
