Carbon full-suspension mountain bike Trek Supercaliber SLR 9.8 X0 Flight Attendant blue: power meter, 11.28 kg

Trek Supercaliber SLR 9.8 X0 Flight Attendant Navy Smoke: train and race with watts

The Gen 2 Trek Supercaliber SLR 9.8 X0 Flight Attendant comes as standard with a SRAM X0 chainset with power meter, the X0 Eagle AXS wireless drivetrain and Flight Attendant electronic suspension, on the OCLV Mountain SLR carbon frame. It weighs 11.28 kg in size M. Its Navy Smoke finish features a smoky navy blue that plays with the reflections of the carbon.

Technical specifications

Who is it for?

For the racer who trains to a structured plan, measures sessions in watts and wants the same data on their XC race bike. It is also aimed at the rider who rides on the road in winter with a power meter and no longer wants a break in their data come spring.

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.

The power meter built into the X0 chainset sends your watts to your computer: on the climbs of the Montagne Noire, you can manage a threshold effort without relying on feel, then analyse your consistency afterwards. For a racer, it is a far more reliable progression tool than heart rate alone.

Flight Attendant also uses your pedalling to decide when to firm up the suspension: when you push on the pedals, the fork and shock stiffen; when you freewheel through a rough section, they open up. The wireless X0 AXS drivetrain completes this coherent electronic package, controlled from a single app.

Which Supercaliber should you choose?

Our take: at 11.28 kg in M, this 9.8 Flight Attendant weighs 100 g less than the 9.8 X0 AXS while adding a power meter and controlled suspension. The 9.9 XX Flight Attendant drops to 10.28 kg with Kovee RSL wheels.
