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 down tube guards, Knock Block 2.0 and 160 mm of travel with a RockShox Super Deluxe shock for long descents and 170 mm RockShox Lyrik Select+ fork. Plus, a SRAM GX Eagle drive train with an extra-low 52-tooth gear and complete 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 drive train makes for a ride that's equally at home on the race course and on a big, backwoods session.

The Walkthrough

favorite_borderWhy you'll love it

  1. A sleek internal storage compartment gives you a versatile spot to stow tools and gear
  2. We added a second down tube guard to better protect your frame from shuttle-related damage
  3. It's equally at home between the tape and in the rugged wild – Yes, Slash is a race bike, but it's ridiculously fun on gnarly trail rides, too
  4. New, removable Knock Block has a bigger steering angle to keep cables and hoses safe without sacrificing turning radius
  5. Wider seat tube, wider dropper – the 34.9 mm diameter post is stronger, more durable, and moves up and down faster

‘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.’

RockShox Super Deluxe Thru Shaft damper

Active Braking Pivot

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

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.

Rapid Drive 54 rear hub

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 Tubeless System

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

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.

Knock Block

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.

Threaded bottom bracket

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.
