Nothing else like it
Supercaliber's unique frame design ditches traditional suspension hardware so there's less weight, less maintenance and less lateral flex. IsoStrut connects the mainframe to the pivot-less seat stays to offer about 60 mm of rear wheel travel. This design offers a unique blend of efficiency, traction and fatigue-fighting compliance that keeps racers fresh and in control.

IsoStrut
IsoStrut integrated suspension gives you just enough travel to stay in control. It's fully tunable like a standard rear shock, but without the weight penalty of a full suspension bike.

OCLV Mountain Carbon
Trek's mountain-specific carbon is engineered to withstand the extreme demands of off-road racing. Advanced analysis allows our designers to create a frame with the best blend of light weight, responsiveness and just enough compliance in the seat stays to eliminate the need for a heavy rear pivot system.

Straight Shot downtube
Straight Shot downtube gives you an extra-stiff frame without adding any weight, so you can stick your line through the rough stuff and still fly up the next climb.

Knock Block
Knock Block has your frame's back when things go wrong. It prevents your handlebars from spinning all the way around in a crash, so your hoses won't get yanked and your controls won't hit the top tube.
