Trek Supercaliber SLR 9.8 X0 Flight Attendant Gen 2 Overview

The Trek Supercaliber SLR 9.8 X0 Flight Attendant Gen 2 is a carbon cross-country mountain bike built with an SLR OCLV Mountain Carbon frame, IsoStrut suspension, and RockShox Flight Attendant suspension components. The frame uses UDH, 80mm of rear travel, and a Trek IsoStrut with RockShox SIDLuxe Flight Attendant RL3 damper.

Front suspension comes from a RockShox SID SL Ultimate fork with Flight Attendant Race Day damper, Stealth DebonAir spring, tapered steerer, Boost110 spacing, 15mm Maxle Stealth axle, and 110mm travel. The drivetrain uses a SRAM AXS pod shifter, SRAM X0 Eagle AXS T-Type rear derailleur, SRAM Eagle XS-1295 10-52T 12-speed cassette, and SRAM X0 Eagle T-Type 12-speed chain.

The crankset is a SRAM X0 Eagle power meter crank with DUB, 34T chainring, T-Type design, and 55mm chainline. Crank length is 170mm on sizes S, M, and ML, and 175mm on sizes L and XL. The bike also uses a SRAM DUB 92mm PressFit bottom bracket.

The wheel setup uses Bontrager Kovee Elite 30 OCLV Mountain Carbon 29-inch wheels with Tubeless Ready construction. The front wheel uses 6-bolt mounting, Boost110 spacing, and a 15mm thru axle, while the rear wheel uses Rapid Drive 108, Boost148 spacing, and a 12mm thru axle. Tire specifications include Pirelli Scorpion XC 29×2.20” and Maxxis Aspen 29×2.4” tubeless-ready tires.

Braking is handled by SRAM Motive Silver 4-piston hydraulic disc brakes with SRAM 6-bolt rotors. Finishing parts include a Verse Short Elite saddle with hollow magnesium rails, Bontrager Line Dropper seatpost, Bontrager RSL integrated OCLV Carbon handlebar/stem, ESI Chunky grips, and FSA IS-2 headset.
