It's right for you if...
You're a serious enduro racer, and you're looking for a high-performance 29er with a premium parts group that throws down on technical descents and then flies back up the mountain to do it all again.
The tech you get
A full OCLV Mountain Carbon frame, a RockShox Lyrik Select Plus 160mm fork with plush DebonAir spring and Charger 2.1 RC damper, and 150mm of rear travel with a RockShox Deluxe RT3 shock with Trek's exclusive RE:aktiv with Thru Shaft damper. Plus, a Shimano XT 1x12 drivetrain and Shimano SLX 4-piston brakes, 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
This is a beast of mountain bike. The tough OCLV Mountain Carbon frame, Bontrager carbon wheels, and high-end spec make Slash 9.8 a ridiculously fast enduro bike. It's so stable and responsive that the faster you go, the better it rides. If you're still on the fence about 29ers in rough stuff, Slash will make you a believer.
favorite_borderWhy you'll love it
- Slash 9.8 is like a mini DH bike: it has the capability of a downhill bike without the downhill weight
- 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
- 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
"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.
