Slash 8 | Trek Bikes

Overview

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.

An aluminum frame built for harsh riding with a threaded bottom bracket, dual downtube guards, Knock Block 2.0, and 160mm of travel with a RockShox Super Deluxe Ultimate shock for long descents and 170mm 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.

Slash 8 puts serious enduro performance within reach with smart choices on spec that won't empty your wallet. The aluminum frame, burly suspension, and 1x12 Eagle drivetrain makes for a ride that's equally at home on the race course and on a big, backwoods session.

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, Slash is a race 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 34.9mm diameter post is stronger, more durable, and moves up and down faster

"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 maneuverability 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."

Features

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

Watch the video

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.

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.

With 108 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.

Suspension Calculator

This suspension calculator will help you optimize your suspension settings for your riding weight. Simply follow the steps to find your best set up.

Complete Tubeless System

Tubeless Ready rims and tires make it easy to ditch the tubes so you get better traction, fewer flats, and less weight. You're ready to roll right 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.

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

Slash is built for the hardest riding in the harshest conditions with a threaded bottom bracket that's more robust than press fit.
