Jamis 2018 Durango 29 Mountain Bicycle.
DURANGO FRAME DESIGN
The Durango frame features a sloping top tube that optimizes stand-over clearance while adding great looks at the same time. The over-sized down tube and head tube to offer plenty of strength, stiffness and fork crown clearance.
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.
COMPLETE SHIMANO SYSTEM
Fully integrated shifting systems offer the most precise and reliable performance. That’s why all of our Durango models feature Shimano shifters, front and rear derailleurs, cassettes and cranksets.
ZERO STACK INTERNAL HEADSET
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 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.
DUAL WATER BOTTLE MOUNTS
Every Durango offers 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 Durango frame offers a replaceable derailleur hanger designed to yield in a crash before the frame does.
