Trek Supercaliber SLR 9.9 Flight Attendant Gen 2 XC Mountain Bike In Red Smoke/Drizzle

Season:2025

Brand:Trek

Code:48043RED

Supercaliber SLR 9.9 Flight Attendant Gen 2 is an ultralight XC mountain bike 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. It’s equipped with a 110 mm fork and 80 mm IsoStrut shock with Flight Attendant tech that delivers free speed with non-stop suspension adjustments as you ride. It's all topped off with carbon wheels, a carbon cockpit and SRAM's lightest wireless direct-mount transmission.

It's right for you if...You. Need. Speed. You want the lightest and fastest cross-country race bike you can find, with tech that’s been proven on the world stage. You want to sprint up climbs and hammer to the finish, and let your bike do the thinking for you with 110 mm front and 80 mm of IsoStrut rear suspension with RockShox Flight Attendant. From wheels to cockpit, you crave carbon and you want the most meticulous high-mod carbon lay-up we offer on a mountain bike.

The tech you get - 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 80mm of IsoStrut rear suspension from a RockShox SIDLuxe shock – all with Flight Attendant tech. An ultralight, fully wireless SRAM XX SL AXS 12-speed electronic transmission, Bontrager Kovee RSL carbon wheels, carbon Bontrager RSL Integrated bar/stem combo, RockShox Reverb AXS wireless dropper post and SRAM Level Ultimate 4-piston hydraulic disc brakes.

The final word - The Supercaliber SLR 9.9 Flight Attendant Gen 2 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 groupset, and RockShox Flight Attendant suspension that automatically adjusts to how and where you’re riding, so you can gain free speed.

Features:
  • You get a 110 mm fork and 80 mm of IsoStrut rear suspension with RockShox Flight Attendant 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 with Flight Attendant and fully wireless direct-mount SRAM XX SL AXS transmission, give you the performance advantage
