Trek Supercaliber SL 9.6 Gen 2
Trek / Cross Country Mountain Bikes
Cross-country speed, with a little cushion.
Supercaliber SL 9.6 is a carbon cross country mountain bike built for rocketing over singletrack and scorching the way to the finish line. It's built with a carbon frame that balances stiffness with compliance for power when you need it most, while IsoStrut rear suspension gives you just enough squish to soften the blow through the rough terrain peppering modern XC courses. It comes ready to rip with a 12-speed SRAM Eagle transmission, so you've got a gear for every climb and breakaway.

The ride, not just the specs
Supercaliber is a cross-country race bike with a touch of rear suspension. It stays light and quick, and takes the edge off the rough sections.
It's the bike for riders who want race speed and a little more comfort over a long day.
What makes it special
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 80mm 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.
Supercaliber SL is a lightweight OCLV Carbon frame. It features a lightweight carbon layup that doesn't compromise stiffness for weight, plus it featuers internal guides that make cable routing a breeze.

“A podium contender for any cross country racer”
...this speedster is closer to being the best of both worlds - great pedaling efficiency combined with reasonable comfort and descending capability. Both Vital testers, who regularly race XC and often take on longer endurance rides and events, said they would buy this World Cup-winning bike.

“It’s a full-on racer and a very capable one at that”
Trek's new cross country race bike has the speed racers dream of. Everybody who has ridden the new Supercaliber has come away seriously impressed and wants more time on it. After their first ride, one was already calling it the fastest bike he had ridden – that’s saying something given the recent crop of test bikes that have passed through our offices lately.

“Supercaliber is pretty super”
It’s a hoot to ride even when someone isn’t recording with a stopwatch, and it’s far more capable than its modest travel figures would suggest. As the testing progressed, I found myself pushing the Supercaliber harder and harder, and on increasingly challenging terrain.
