It's right for you if...

You're gunning for the top spot and looking for a pro-level cross country race bike that has top-of-the-line everything. You want a bike that comes spec’d with the best parts and suspension available—including a fully wireless electronic drivetrain—for knock-out, drag-out speed and capability.

The tech you get

An ultra-lightweight, full OCLV Mountain Carbon frame with 60mm of travel, a 100mm RockShox SID Ultimate fork, and Trek's exclusive IsoStrut FOX Factory shock designed specifically for Supercaliber. Plus, a fully wireless SRAM XX1 Eagle AXS 1x12 electronic drivetrain, Bontrager carbon wheels with a 54-tooth DT Swiss rear hub for fast engagement, SRAM Level Ultimate brakes with carbon levers, and a Bontrager XXX carbon seatpost and handlebar.

The final word

If you don’t podium, sorry, but you can’t blame it on this bike. Its insanely light carbon frame is spec'd for the pros using the most advanced MTB components out there, including our cutting-edge IsoStrut integrated shock and a fully wireless SRAM XX1 Eagle AXS drivetrain.

Features

Nothing else like it

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

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

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 w/Knock Block

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.
