Technical specifications

Who is it for?

For the marathon racer who lines up for raids and the big regional classics and wants to reach the end of the event with a clear head. It will also suit the very experienced rider who rides alone for hours in the hinterland and wants the most efficient bike possible.

The LVR workshop view

OCLV carbon, Trek's signature. Since 1992, Trek has heat-pressed its fibre sheets to eliminate the air pockets that weaken a frame. The OCLV Mountain version is calibrated for off-road use: it has to withstand rock strikes and crashes, not just be stiff. On this flagship, it is the SLR version, the lightest in Trek's mountain bike catalogue, that forms the frame; it remains covered by Trek's lifetime warranty.

In short: the 9.9 XX Flight Attendant does not change frame compared with the other SLRs; it brings together the very best Trek does around it: XX SL drivetrain, Motive Ultimate brakes, carbon wheels and electronic suspension. The result is the lightest Supercaliber in the range, 300 g under the 9.9 XTR Di2.

In a marathon, fatigue makes you forget to lock the suspension on a climb or open it again on the next descent. Flight Attendant does it for you, at every change of gradient: the fork stays firm on the long tracks of the Espinouse, then opens as soon as the trail gets rough.

The Fox Transfer SL post, with 100 to 150 mm of travel depending on size, drops the saddle without taking your hands off the bar for the technical descents of the Caroux. With Kovee RSL carbon wheels and Pirelli Team Edition tyres, the bike stays light to accelerate, even after four hours in the saddle.

Which Supercaliber should you choose?

Our take: for long distances, this 9.9 XX Flight Attendant offers the best balance of weight and effort management. The 9.8 X0 Flight Attendant keeps the same automated suspension and adds a power meter, for 1 kg more in M.
