It's right for you if...

You want a high-value head start on your enduro build and the kind of trail tech that comes only from a long heritage of all-mountain riding. You like to go fast, go big, and rail corners, and you're looking for a big bike that will stand up to whatever wild trails you can find.

The tech you get

A burly Alpha Platinum Aluminum frame with Control Freak internal routing, 160mm of travel with a RockShox Super Deluxe Select+ shock with plush DebonAir spring and Select+ damper, a 35mm Bontrager Line stem, and an integrated Knock Block 2.0 headset that stops spinning bars and the fork crown from hitting your frame. Built for 29er wheels and a 170mm or 180mm fork.

The final word

With Slash AL Frameset, you're getting a whole lot of capability for your money and a great start on a bike that can handle the burliest trails out there. Whether you're racing or looking to get sendy, this burly frameset will stand up to whatever you throw at it.

The Walkthrough

favorite_borderWhy you'll love it

  1. 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
  2. A large internal storage compartment in the down tube lets you stow tools and gear
  3. Mino Link lets you adjust the geometry, so you get both an enduro race bike and an ultra-capable trail bike in one
  4. New, removable Knock Block has a bigger steering angle to keep cables and hoses safe without sacrificing turning radius

Features

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.

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.

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.
