  • Nothing else like it

    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 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

    IsoStrut

    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.

  • SLR OCLV Mountain Carbon

    SLR OCLV Mountain Carbon

    Supercaliber SLR is the World Cup lightweight frame. It drops grams by using a higher modulous carbon fiber layup that allows us to use less material, plus we skip internal guide tubes for cable routing, minimizing material and maximizing weight savings.

    Get speed-enhancing technology right at the fingertips. XTR Di2 is Shimano's lightest and most robust MTB groupset ever, with the lightening-fast shifts and die-hard reliability you've come to expect from Shimano. Plus, it's now wireless and more customizable than ever.

  • You almost forgot your pedals

    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 & efficiency.

Overview

Supercaliber SLR 9.9 XTR is an ultralight carbon XC mountain bike equipped with the top components for race day. Its SLR Mountain Carbon frame is as light as it is meticulous, with a high modulus layup that gives you all the stiffness you crave and none of the weight. XC courses get rowdier every year, so it comes equipped with a 110mm fork and 80mm of IsoStrut rear suspension to smooth your roll without kicking pedaling efficiency to the wind. It's all topped off with carbon wheels, a carbon cockpit, and lightning-fast shifting from Shimano's all-new iconic XTR Di2 wireless drivetrain.
