Slash 9.9 XX1 AXS Flight Attendant

Overview

You're looking for the kind of enduro bike that can rip it up on the world’s biggest stage. You want the very latest tech like electronic shifting and the new Flight Attendant electronic damper from RockShox.

A full OCLV Mountain Carbon frame with 160 mm of travel and a RockShox Super Deluxe Ultimate shock with an updated Thru Shaft damper, a RockShox ZEB Ultimate fork with extra-beefy 38 mm stanchions. Plus, RockShox Flight Attendant wireless electronic damping control automagically adjusts your suspension to best suit the terrain. A wireless electronic SRAM X01 Eagle AXS drivetrain with a 10-52 cassette, Reverb AXS dropper, Bontrager RSL integrated bar/stem, and Line Pro 30 carbon wheels with a 108-tooth Rapid Drive hub.

There's not a single part on this bike that wasn't made for ripping it up at insane speeds on the wildest enduro courses in the world. And you get RockShox Flight Attendant that automatically adjusts your suspension damping so you can focus on flying down the trail.

The RockShox ZEB fork's bigger 38 mm stanchions help you stay on your line through the chunky stuff, while the updated damper lets you dial in the feel
The OCLV Carbon RSL integrated bar/stem is ultra-light and ultra-comfortable, and it looks awesome
RockShox Flight Attendant uses wireless sensors in the fork, shock and crank to automatically adjust your suspension damping to the terrain. It's one less distraction from the trail ahead
Wider seat tube, wider dropper – the 34.9 mm diameter post is stronger, more durable, and moves up and down faster
A large internal storage compartment in the down tube lets you stow tools and gear

'The combination of high-end performance with individuality and user-friendliness in the thought-through package delighted the entire jury.'

‘The Slash has a big-bike feel that makes it easier to charge into an unfamiliar trail, while retaining enough manoeuvrability to prevent it from feeling like overkill on mellower trails.’

Once the dust had settled, it was the Slash that managed to edge its way into the lead. Its ability to tackle the wildest terrain without flinching yet all the while retaining that reactive, lively feel really won us over.

‘Slash is great on rough, bermed corners and it has been an absolute monster riding steeps. This is an easy bike to ride and everything felt very natural from the first drop in and I haven’t looked back since.’

Transitions? Tech zones? Walking?! It's Enduro 101 and Pinkbike's Christina Chappetta is here to break down everything you need to know before you line up between the tape.

Features

Using SRAM AXS technology, Flight Attendant analyses 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.

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.

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.
