Carbon full-suspension mountain bike Trek Supercaliber SLR 9.8 X0 Flight Attendant red: wireless, 11.28 kg

Trek Supercaliber SLR 9.8 X0 Flight Attendant Red Smoke: the way into controlled suspension

The Gen 2 Trek Supercaliber SLR 9.8 X0 Flight Attendant is the most direct way to get RockShox electronic suspension on a Supercaliber, with the OCLV Mountain SLR carbon frame, the SRAM X0 AXS wireless drivetrain and Kovee Elite 30 carbon wheels. It weighs 11.28 kg in size M. Its Red Smoke/Drizzle colour mixes a rich smoky red with fine light speckles.

Technical specifications

Who is it for?

For the racer or sporty mountain biker curious about new technology who wants to enjoy controlled suspension without going all the way to the top model. It will also suit the rider who often forgets to lock or unlock their suspension on a ride.

The LVR workshop view

OCLV carbon, Trek's signature. Trek developed OCLV in the early 1990s: compaction under pressure and temperature that drives out the air trapped between the fibre plies. For mountain biking, the brand created OCLV Mountain, whose priority is impact resistance rather than weight saving alone. The 9.8 X0 Flight Attendant benefits from the SLR variant, the finest, with the same lifetime warranty as every Trek frame.

Put simply: this 9.8 brings Flight Attendant suspension and a power meter for 100 g less than the standard 9.8 X0 AXS. It does not change the wheels or brakes of the rest of the 9.8 range: for the lightest version, you need to move up to the 9.9 XX Flight Attendant.

With no wires between the controls and the X0 AXS derailleur, the cockpit stays clean and the build simpler: the one-piece RSL bar-stem only carries the brake hoses. Shifts stay precise under load thanks to the T-Type cassette mounted directly on the UDH universal hanger.

The Kovee Elite 30 carbon wheels offer good lateral stiffness in corners and an internal width that supports 2.2 to 2.4-inch tyres well. Flight Attendant, meanwhile, is set up from the SRAM app: you can choose firmer behaviour for racing or softer for sporty rides.

Which Supercaliber should you choose?

Our take: this 9.8 Flight Attendant brings controlled suspension and a power meter for 100 g less than the 9.8 X0 AXS. The 9.9 XTR Di2, 700 g lighter, keeps manual suspension.
