The Supercaliber SLR 9.9 XX AXS is an ultra-light XC mountain bike that's built with the top components for race day. Its SLR Mountain Carbon frame is as light as it is meticulous, with a high modulus lay-up that gives you all the stiffness you crave and none of the weight. XC courses get rowdier every year, so it's equipped with a 110 mm fork and 80 mm of IsoStrut rear suspension to smooth your roll without dropping pedalling efficiency. It's all topped off with carbon wheels, a carbon cockpit and SRAM's lightest wireless direct-mount transmission.

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 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
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.

SLR OCLV Mountain Carbon
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.

You almost forgot your pedals
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.
