$869.99

TRAIL X SERIES

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.

Description

FRAME MATERIALS

Lightweight and strong 6061 series aluminum tubing, featuring over-sized & tapered tubing for increased frame stiffness.

PEDALING PLATFORM

The aluminum frame of the Trail X and Helix is beefed up to include a larger 34.9mm seat tube, which allows us to spec an over-sized 31.6mm seat post. The larger diameter post flexes less, providing a firmer pedaling platform.

Top Tube Cable Routing

Running the cables up under the top tube keeps cables and housing out of the muck for more precise and reliable shifting performance.

ZERO STACK Internal Headset

A Zero Stack internal headset places both the cups and bearings inside the head tube instead of outside. This reduces the total stack height (including the head tube), which is beneficial on larger wheeled bikes. The larger diameter head tube also provides a larger weld interface at the critical head/top/down tube junction.

Dual Water Bottle Mounts

Most of our Trail X sizes offer two water bottle mounts located inside the main frame. This provides excellent hydration capacity in an easily accessible position.

Replaceable Derailleur Hanger

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

Full Shimano Shifting System

Fully integrated shifting systems offer the most precise and reliable performance. That’s why our Trail X and Helix models all offer Shimano shifters, Shimano front and rear derailleurs and Shimano cassettes or freewheels.

Alex TD26 Disc-Specific Rims

Disc hubs twist during braking. This twisting increases “pull” load on the nipples in the spoke bed. The Alex TD26 spoke bed on the rims specified on Expert, Comp and Sport is cleverly reinforced to resist disc brake torque and prevent spokes & nipples from shearing.
