Overview
About this bike
SE's Big Mountain 27.5 is just at home on your commute to work on the bike path as it is on your local ribbon of singletrack. Your daily shred just got a little zestier thanks to the light aluminum frame mated to a 80mm-travel suspension fork that soaks up trail chatter. The real zippiness comes from the 27.5-inch wheels wrapped in Hutchinson tires so you navigate, overcome, and accelerate confidently on any trails, anywhere. Getting up to speed is a smooth endeavor too thanks to the slick-shifting Shimano 21-speed drivetrain that gives you a wide range of gears for the ups, downs, and flats in between. The Big Mountain is topped off with linear-pull brakes that scrub your speed for expert control, not to mention a smattering of rugged components from Kore that keep you on the trails for years to come.
