Overview
About this bike
There was a time when every mountain bike was an all-around hardtail. Climbs, descents, berms, even some air: the Line does its hardtail predecessors proud. This bike is far from a throwback or retro project though — it's a modern machine. The slack and low-slung frame is the key: it lowers your center of gravity, keeping you stable any speed. A single-ring SRAM 1×9 drivetrain, short stem, and wide bars complement its contemporary configuration. Hydraulic disc brakes with big rotors and 27.5to; knobbies give you tons of traction and stopping power. If you’re looking for a bike that can really do it all: look no further. The Line makes every trail more fun.
