It's right for you if...
You want a high-value head start on your enduro build and the kind of trail tech that comes only from a long heritage of all-mountain riding. You like to go fast, go big, and rail corners, and you're looking for a big bike that will stand up to whatever wild trails you can find.
The tech you get
A burly Alpha Platinum Aluminum frame, 150mm of travel with a RockShox Deluxe RT3 shock with Trek's exclusive RE:aktiv damper, a 35mm Bontrager Line stem, and an integrated Knock Block headset that stops spinning bars and the fork crown from hitting your frame. Built for 29er wheels and a 150mm or 160mm fork.
The final word
With Slash AL Frameset, you're getting a whole lot of capability for your money and a great start on a bike that can handle the burliest trails out there. Whether you're racing or looking to get sendy, this burly frameset will stand up to whatever you throw at it.
The Walkthrough
favorite_borderWhy you'll love it
- RE:aktiv keeps the shock firm for efficient pedaling and pumping, and instantly soaks up bumps to keep 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
"One of the best"
"It felt like we just unlocked a super power. Speeds increased, cornering confidence went way up, and traction gains made us feel like pushing harder. It's clear this bike was made to move."

"Eats up everything"
"It’s for big mountain days, crushing rock filled descents and popping off the lips of jumps all while climbing back to the top with a smile on your face."

"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."

"Perfect do-it-all enduro bike"
"Going downhill, the handling is impressively versatile. It’s agile, but not nervous, composed, but not cumbersome. No matter which trail you’re on, with the Trek you’re on the right bike."

Control Freak Cable Management
The lightest, quietest, most versatile cable management system allows any combination of shift, brake, lockout, and dropper post lines to be routed through the frame for clean looks and the ultimate custom setup.
Boost148/110
Wider dropouts (110mm front, 148mm rear) give you the stiffness of a 27.5" wheel with all the benefits of a 29" wheel, and Boost148 in the rear lets you run wider tires and a larger chainring without affecting q-factor and pedaling efficiency.

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.
