"The new XC race benchmark"
"It's simply everything you want from an XC race bike. If someone riding a Supercaliber beats you next season, take solace in the fact that their bike is faster than yours."

"Does it deliver? Yes!"
"Locked out, Supercaliber climbs as well as a fully rigid bike, but with the fork and shock open, the bike has gobs of traction heading uphill and minimal pedal feedback in the suspension. Descending, it's much more sure-footed in technical terrain than a hardtail and feels like it has way more travel than it really does."

"Too hard core to be a soft tail"
"Half hardtail, half full suspension. This is a unique animal meant for other unique animals - XC racers. Designed for the top-level, dedicated cross country racer."

Features
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 60mm 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 integrated suspension gives you just enough travel to stay in control. It's fully tuneable 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.
Trek's Straight Shot frame design optimizes the stiffness-to-weight ratio for a more responsive ride. You'll be able to push harder and stay more planted on your line when the going gets rough.

Sizing & fit
The charts below show our recommended sizes based on height, but there are some other factors, like arm and leg length, that determine a great fit. That’s why you’ll see some overlap in our recommendations. Not every rider who’s 5´8˝, for example, will fit on the same size bike. The best way to find your perfect fit is to consult the experts at your local Trek retailer.
