Jamis Helix Sport 2018

Jamis Helix Sport 2018


Building great recreational-level bikes for both men and women that ride much like our hi-end bikes is a passion at Jamis. And no bikes showcase our commitment to do just that better than these. The 27.5” wheel size is not a compromise between 26” or 29”: it’s the best of both worlds. The Helix chassis emphasizes all-day performance and quick handling without being overly darty. Low standover, short reach stems and brakes, wide range gearing and gender specific saddles are just some of the features of the highly capable Helix line-up.
