WHAT Lightweight, fully butted, proprietary M4 Aluminum tubing; full internal cable routing.
WHY M4 Aluminum tubing creates the best balance of weight, strength and compliance combined with a clean look.
HOW By controlling everything from the raw material to the extrusion, butting, swaging and heat treatment of the tubes we can optimize our Crosstrail frame for an extreme light and stiff all-road experience. All cables are routed inside the frame so the bike looks completely organized and clean.
