OverviewBuilding great recreational-level bikes that ride much like our hi-end bikes is a passion at JAMIS. No bikes showcase our commitment to do just that better than these. The trail x 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're more than able to keep up.
