Overview
About this bike
Building great recreational-level bikes that ride much like (and look a lot like) our hi-end bikes is a passion at Jamis. And no bikes showcase our commitment to do just that better than these. The Trail X and Helix chassis emphasizes all-day performance and the handling’s quick and sure without being overly darty. But make no mistake, if you want to throw down, they more than able to keep up with 27.5” wheels, precise shifting drivetrains and incredibly powerful disc or linear pull brakes.
