It's right for you if...

You’re an all-mountain rider who loves pinning steep descents and sketchy rock gardens. You want a bike that’s born to plow through the roughest stuff at full tilt, is fully capable of racing enduro, and doesn’t ring up at a bank-breaking price.

The tech you get

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 Select+ shock and 170mm Yari RC fork. Plus, a SRAM NX Eagle drivetrain and Line Comp 30 wheels that are already completely tubeless ready, including sealant.

The final word

It may be the most affordable Slash in the lineup, but don’t underestimate how fast it'll carry you down the mountain. You get a frame built for day after day of hard riding with a no-nonsense parts package that leaves enough cash in your pocket for enduro entry fees or a lift ticket to party laps.

The Walkthrough

favorite_borderWhy you'll love it

  1. It's equally at home between the tape and in the rugged wild—Slash excels at racing enduro, but it's ridiculously fun on gnarly trail rides, too
  2. A sleek internal storage compartment gives you a versatile spot to stow tools and gear
  3. We added a second down tube guard to better protect your frame from shuttle-related damage
  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 34.9mm diameter post is stronger, more durable, and moves up and down faster

Features

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.

Sizing & fit

The charts below show our recommended sizes based on height, but there are some other factors, like arm and leg length, that determine a great fit. That’s why you’ll see some overlap in our recommendations. Not every rider who’s 5´8˝, for example, will fit on the same size bike. The best way to find your perfect fit is to consult the experts at your local Trek retailer.
