Supercaliber 9.9 is the fastest, lightest and most capable cross-country race bike we make - and that's exactly why it's Trek Factory Racing's World Cup bike of choice. The exclusive IsoStrut top tube shock is the cornerstone of Supercaliber's efficient suspension system, giving you a fast and light ride that charges through rugged terrain at breakneck speed.

You're gunning for the top spot and looking for a pro-level cross country racing bike that has top-of-the-line everything. You want a bike that comes spec'd with the best parts and suspension available - plus tons of carbon - for knock-out, drag-out speed and capability.

An ultra-lightweight, full OCLV Mountain Carbon frame with 60 mm of travel, a 100 mm RockShox SID SL Ultimate fork with Charger Race Day damper and Trek's exclusive IsoStrut FOX Factory shock designed specifically for Supercaliber. Plus, a full Shimano XTR 1x12 drive train, Bontrager Kovee XXX 30 carbon wheels with a 54-tooth rear hub for fast engagement and a Bontrager XXX carbon seat post and handlebars.

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. Saddle up and see what you're made of.

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.

Rapid Drive 108 rear hub
With 108 points of engagement, Rapid Drive gives you nearly instant acceleration instead of a clunky lag when you step on the pedals. You get smooth, immediate power to blast out of corners and hammer through the rough stuff. And that extra pedal ratchet adds control that can make all the difference when tackling a tricky 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.
