Trek Slash 9.9 Xx1 Flight Attendant Mountain Bike

RockShox Flight Attendant

Using SRAM AXS technology, Flight Attendant analyzes data from sensors on the fork, shock, and crank to automatically shift between compression damping modes before the thought ever crosses your mind. It does the thinking for you so you can stay focused and in the zone.

RockShox Super Deluxe Thru Shaft damper

With the all-new RockShox Super Deluxe Ultimate Thru Shaft, you get the most refined shock on the market, with an updated air spring and an exclusive Thru Shaft damper that gives you tenacious grip, plush control, and the support you need for ripping rough descents all day.

BITS: Your trailside savior

Cleverly integrated into the steerer tube, the included BITS multi-tool has everything you need for trailside adjustments and repairs.

Active Braking Pivot

Active Braking Pivot allows our engineers to tune how the suspension reacts to acceleration and braking forces independently. That means you get more confident control when you need it most.

Complete frame protection

Replaceable down tube guards protect the underside of your frame from rock strikes, trail debris, and janky shuttle vehicles so you can forget about damage worries and focus on blasting the next run.

OCLV Mountain Carbon

Trek’s mountain-specific carbon fiber is tougher carbon, with unique materials and layup procedures, Trek’s advanced engineering, and a higher standard of testing.

Internal Storage

Internal frame storage makes it easy to ditch the pack and still carry your ride essentials.
