Helix A2 27.5 Sport Hardtail Mountain Bike

Building great recreational-level bikes that ride much like our high-end bikes is a passion at Jamis. No bikes showcase our commitment to do just that better than these. The Helix chassis emphasizes all-day performance with quick, but not overly twitchy handling attributes. Make no mistake though, if you want to throw down they’re more than able to keep up.

Because it’s much easier and much less expensive to replace a derailleur hanger than it is to repair or replace a frame, every Helix frame offers a replaceable derailleur hanger designed to yield in a crash before the frame does.
