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

Alpha Platinum Aluminum
Our premium lightweight aluminum is continuously cold extruded and butted at multiple points, and hydroformed into sophisticated tube shapes for maximum strength and minimum weight.
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.
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.
