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 Aluminum frame, a 160mm RockShox Yari RC fork, and 150mm 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 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.
favorite_borderWhy you'll love it
- RE:aktiv with Thru Shaft works faster than a normal shock, so it tracks the ground better and keeps you in control
- Mino Link lets you adjust the geometry, so you get both an enduro race bike and an ultra-capable trail bike in one
- 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
"Sort of magic"
"You could spend less on a YT, Canyon or Fezzari, get nicer parts, a carbon frame, and you’d probably be happy as a clam—just as long as you never threw a leg over this bike. There’s a sort of magic about it that has me wanting to ride it over my other, much fancier bikes."Read more

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.
