It's right for you if...

You're looking for the kind of performance advantages that come only from the kind of enduro race bikes that rip it up on the World Tour. You like going fast, getting rowdy, and railing corners all the way to the top step of the podium.

The tech you get

A full OCLV Mountain Carbon frame, a RockShox Lyrik Ultimate 160mm fork with a Charger 2 RC2 damper, and 150mm of rear travel with a RockShox Deluxe RT3 shock featuring Trek's exclusive RE:aktiv with Thru Shaft damper. Plus, a SRAM X01 Eagle 1x12 drivetrain, Bontrager Line Elite dropper post, Bontrager Line Pro carbon bars, and Bontrager Line Carbon 30 wheels with a 54-tooth Rapid Drive hub for quick acceleration when you need it most.

The final word

There's not a single part on this bike that wasn't made for ripping it up at insane speeds on the wildest enduro courses in the world. Fast, tough, fast, fun, fast. Did we mention this bike is fast?

favorite_borderWhy you'll love it

  1. RE:aktiv with Thru Shaft works faster than a normal shock, so it tracks the ground better and keeps you in control
  2. 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
  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. Control Freak Cable Management allows you to run any combination of cables exactly the way you want, while still giving you sleek looks and protecting your cables against unnecessary wear

    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.
