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 want the swift, precise shifting of a wireless electronic drivetrain, and you like going fast, getting rowdy, and railing corners all the way to the top step of the podium.
The tech you get
A stout OCLV Mountain Carbon frame, a 160mm RockShox Lyrik Ultimate fork with plush DebonAir spring and Charger 2 RC2 damper that gives you more adjustment and control, and 150mm of rear travel with a RockShox Deluxe RT3 shock featuring Trek's exclusive RE:aktiv with Thru Shaft damper. Plus, a fully wireless SRAM X01 Eagle AXS 1x12 electronic drivetrain and RockShox Reverb AXS dropper post, powerful Shimano XT 4-piston hydraulic disc brakes, Bontrager Line Carbon 30 wheels with a 54-tooth Rapid Drive hub for quick acceleration when you need it most, and a Bontrager Line Pro OCLV carbon handlebar.
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. It has high-end everything, including a fully wireless drivetrain and dropper post. Slash 9.9 is fast, tough, fast, fun, fast. Did we mention this bike is fast?
favorite_borderWhy you'll love it
- The SRAM X01 Eagle AXS drivetrain is smart, smooth, and completely wireless
- RE:aktiv with Thru Shaft works faster than a normal shock, so it tracks the ground better and keeps you in control
- 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
- Mino Link lets you adjust the geometry, so you get both an enduro race bike and an ultra-capable trail bike in one
- Make it yours: it's fully customizable through Project One
"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.
