Lightweight and strong 6061 series aluminum tubing, featuring over-sized & tapered tubing for increased frame stiffness.
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 frame offers a replaceable derailleur hanger designed to yield in a crash before the frame does.
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 all Trail X models are cleverly reinforced to resist disc brake torque and prevent spokes & nipples from shearing.
