Running the cables up under the top tube keeps cables and housing out of the muck for more precise and reliable shifting performance.
Durangos feature a Zero Stack internal headset that 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 especially beneficial on big wheeled bikes. The larger diameter head tube also provides a larger weld interface at the critical head/top/down tube junction.
Top-notch braking shouldn’t break the bank. Disc brakes offer the power, all-day, all-conditions reliability.
Because it’s much easier and much less expensive to replace a derailleur hanger than it is to repair or replace a frame, every Durango frame offers a replaceable derailleur hanger designed to yield in a crash before the frame does.
Every Durango offers two water bottle mounts located inside the main frame. This provides excellent hydration capacity in an easily accessible position.
The aluminum frame on the Durango 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.
Lightweight and strong 6061 series aluminum tubing, featuring over-sized & tapered tubing for increased frame stiffness.
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.
HELIX
Building 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 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're more than able to keep up.
