It's right for you if...

You're a mountain biker's mountain biker, and you want a big bike with big wheels to roll over big things that get between you and the next big hit. This bike is both fully capable of handling enduro races, and a whole lot of fun on rowdy trails.

The tech you get

A trail-tough Alpha Platinum Aluminium frame, a 160 mm RockShox Yari RC fork and 150 mm of rear travel with a RockShox Deluxe shock with Trek's ultra-responsive RE:aktiv with Thru Shaft damper. Plus, a SRAM GX Eagle 1x12 drivetrain, a Bontrager Line dropper post and Bontrager Line Comp 30 wheels with a 54-tooth Rapid Drive rear hub for fast engagement.

The final word

Slash 8 puts serious enduro performance within reach with smart choices on spec that won't empty your wallet. The Alpha Aluminium 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.

The Walkthrough

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. Mino Link lets you adjust the geometry, so you get both an enduro race bike and an ultra-capable trail bike in one
  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. We're not the only ones who love it: Slash was awarded Mountain Bike of the Year by Pinkbike

Tubeless Ready

Tubeless Ready rims and tyres make it easy to ditch the tubes so you get better traction, fewer flats and less weight. The rim strips are already installed; just add TLR valves and sealant.

Mino Link adjustable geometry

Fine tune head tube angle by 1/2° and BB height by up to 10mm with the simple turn of a nut. Just flip the link to choose between slack or slacker geometry, without negatively affecting suspension performance. A Trek exclusive.
