Supercaliber SLR 9.9 XX AXS Gen 2

Overview

'... 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.'

'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.'

'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.'

'… an unapologetic and uncompromising cross-country racing machine. The bike is absolutely world-class when it comes to going uphill.'

Features

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 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.

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.

Sizing

How tall are you?

To measure your height, stand up straight, barefoot, with your back, heels, shoulders and head all touching a wall. While looking straight ahead, place a book or straight edge on your head and slowly push it against the wall. Your straight edge should be parallel with the floor. Mark the spot where the bottom of the book is touching the wall. The distance from the marked spot to the floor is your height.

What is your inside leg?

How to measure: Stand barefoot with your back straight and against a wall. Tuck a ruler or something that extends to the floor between your legs. Using both hands, and keeping it level, pull the ruler up into your crotch as if you were sitting on the saddle. Measure the distance from the top edge of the ruler to the ground to find your inside leg measurement. Your inside leg is very important to your final bike size so please measure carefully.
