Slash 9.9 XX1 AXS - Trek Bikes (IE)

Overview

You're looking for the kind of enduro bike that can rip it up on the world’s biggest stage. You like going fast, getting rowdy and railing corners, and you want top-shelf electronic components that can keep up.

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. 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. Fast, tough, fast, fun, fast. Did we mention that this bike is fast?

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
We added a second down tube guard to better protect your frame from shuttle-related damage
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.

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.

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.

Trek's mountain-specific carbon fibre is tougher carbon, with unique materials and lay-up procedures, Trek's advanced engineering, and a higher standard of testing.
