New Arrivals/Restock

Supercaliber SLR 9.9 XX Flight Attendant is an ultralight XC mountain bike thats built 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 its equipped with a 110mm fork and 80mm of IsoStrut rear suspension to smooth your roll without dropping pedaling efficiency. Its all topped off with carbon wheels, a carbon cockpit, and SRAMs lightest wireless direct-mount transmission.

• You get a 110mm fork and 80mm of IsoStrut rear suspension that partners with slacker, capable geometry for handling the roots and rocks of modern XC courses
• You dont have to compromise stiffness for weight savings thanks to the SLR OCLV Mountain Carbon frame thats 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 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 integrated suspension gives you just enough travel to stay in control. Its fully tuneable 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 fiber layup that allows us to use less material, plus we skip internal guide tubes for cable routing, minimizing material and maximizing weight savings.

Rockshox Flight Attendant

Flight Attendant analyzes 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.

Adaptive Ride Dynamics

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 personalized Effort Zones for total suspension customization.

You almost forgot your pedals

This bike doesn’t come with pedals because youll 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.
