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.

You're in it for the podium. You want an ultra-light, ultra-capable XC machine that's proven on the world stage. You want to sprint up climbs and hammer to the finish, and feel good doing it thanks to 80 mm of IsoStrut rear suspension. From wheels to cockpit, you crave carbon and you want the most meticulous high-mod carbon lay-up we offer on a mountain bike.

A featherweight, high-modulus SLR OCLV Mountain Carbon frame with modern XC geometry. 110 mm of front suspension from a RockShox SID SL Ultimate fork with DebonAir spring and Charger Race Day damper and 80 mm of IsoStrut rear suspension from a RockShox SIDLuxe shock ? all with remote lockout. An ultralight, fully wireless SRAM XX SL AXS 12-speed electronic transmission, Bontrager Kovee RSL carbon wheels, carbon Bontrager RSL Integrated bar/stem combo, Fox Transfer SL dropper post and SRAM Level Ultimate 4-piston hydraulic disc brakes.

The Supercaliber SLR 9.9 XX AXS is bred for racing and comes from a pedigree of champions. You get our top carbon XC full-suspension frame dripping with carbon components and SRAM's lightest fully-wireless group set that keeps going after the cows come home.
- You get a 110 mm fork and 80 mm of IsoStrut rear suspension that partners with slacker, capable geometry for handling the roots and rocks of modern XC courses
- You don't have to compromise stiffness for weight savings thanks to the SLR OCLV Mountain Carbon frame that's intensely light, stiff and responsive
- IsoStrut gives you tunable, damped suspension without missing out on efficiency for hammering up climbs at top speed
- Pivotless seat stays save on weight and actively bend to help soak up trail chatter
- Cream-of-the-crop components, like a RockShox SID Ultimate fork and fully wireless direct-mount SRAM XX SL AXS transmission give you the performance advantage

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 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.
