It's right for you if...
You want a big bike with big wheels to roll over big things and send big hits. You might enter some enduro races, but you mostly just want to rail sketchy descents faster than anyone else in your crew.
The tech you get
An aluminium frame built for harsh riding with a threaded bottom bracket, dual downtube guards, Knock Block 2.0 and 160 mm of travel with a RockShox Super Deluxe Ultimate shock for long descents and 170 mm RockShox Lyrik Select+ fork. Plus, a SRAM GX Eagle drivetrain with an extra-low 52-tooth gear, Code R 4-piston brakes and completely tubeless Line Comp 30 wheels.
The final word
Slash 8 puts serious enduro performance within reach with smart choices on spec that won't empty your wallet. The aluminium frame, burly suspension and 1x12 Eagle drivetrain makes for a ride that's equally at home on the race course and on a big, out-in-the-wild session.
The Walkthrough
favorite_borderWhy you'll love it
- A sleek internal storage compartment gives you a versatile spot to stow tools and gear
- We added a second down tube guard to better protect your frame from shuttle-related damage
- It's equally at home between the tape and in the rugged wild – Yes, the Slash is a racing bike, but it's ridiculously fun on gnarly trail rides, too
- New, removable Knock Block has a bigger steering angle to keep cables and hoses safe without sacrificing turning radius
- Wider seat tube, wider dropper – the 34.9 mm diameter post is stronger, more durable, and moves up and down faster
Winner – Mountain Bike category

‘Feels exactly right’
‘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.’

‘A hell of a bike’
‘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.’

‘Doesn’t just tick all the boxes, it slashes them’
‘It’s playful enough to pop lips and gun for natural trail doubles, yet stable enough to stay planted in the steepest, gnarliest rock gardens I could seek out. The Slash is an absolute joy to ride, and the faster and harder you push it, the more at home it feels.’

RockShox Super Deluxe Thru Shaft damper

Internal frame storage makes it easy to ditch the pack and still carry your ride essentials.
Rapid Drive 54 rear hub
With 54 points of engagement, Rapid Drive gives you nearly instant acceleration instead of a clunky lag when you step on the pedals. You get smooth, immediate power to blast out of corners and hammer through the rough stuff. And that extra pedal ratchet adds control that can make all the difference when tackling a tricky climb.
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.
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 Tubeless System
Tubeless Ready rims and tyres make it easy to ditch the tubes so you get better traction, fewer flats and less weight. You're ready to roll straight out of the box with the included TLR rim strips, valves and sealant.

Oversized 34.9mm dropper post
Bigger is better. The oversized seat tube diameter gives more support and strength for longer travel droppers, and allows for more robust, durable internals that work faster.

Threaded bottom bracket
Slash is built for the hardest riding in the harshest conditions with a threaded bottom bracket that's more robust than press fit.
Knock Block
Knock Block has your frame's back when things go wrong. It prevents your handlebars from spinning all the way around in a crash, so your hoses won't get yanked and your controls won't hit the top tube.
