'... this speedster is closer to being the best of both worlds – great pedalling 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.'
Read more'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.'
Read more'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.'

Read moreSupercaliber’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 80 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 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.
Supercaliber SLR is the World Cup lightweight frame. It drops grams by using a higher modulous carbon fibre lay-up that allows us to use less material, plus we skip internal guide tubes for cable routing, minimising material and maximising weight savings.
Flight Attendant analyses data from sensors on the fork, shock and crank to automatically adjust your suspension between Open, Pedal and Lock positions before the thought ever crosses your mind. It does the thinking for you so you can stay focused and in the zone.
The Supercaliber comes with a crank-based power meter that allows Flight Attendant to collect rider and trail inputs in real time. Adaptive Ride Dynamics compiles data from your previous rides to calculate personalised Effort Zones for total suspension customisation.
This bike doesn’t come with pedals because you'll have a better ride if you choose your own. See the pedal guide to find the best pedals for your riding style. Want pedals built for the race? We recommend clipless MTB pedals for control and efficiency.
