The tech you get
A light and stiff carbon frame with trail-smoothing IsoSpeed, a 100mm RockShox Judy SL fork with Solo Air spring and a TurnKey lockout, a smooth-shifting Shimano Deore 1x12 drivetrain, powerful Shimano hydraulic disc brakes, and fast, tubeless ready 29" wheels.

The Walkthrough
favorite_borderWhy you'll love it
- You're getting into a carbon race bike at an awesome price
- The IsoSpeed decoupler and carbon frame makes it ride smoother than any other hardtail, so your body doesn't get beat up by trail chatter
- You get a Straight Shot downtube for extra-stiff, responsive handling without added weight, and a Knock Block headset that protects against spinning bars and fork crowns
- The RockShox fork's Solo Air spring can easily be adjusted for a specific rider weight, and it's lighter than a coil spring
10/10 Editor's choice

Features
IsoSpeed smooth
IsoSpeed takes the edge off body-beating small bumps and trail chatter so you can stay stronger longer, without giving up any pedaling efficiency.
Trek's mountain-specific carbon fiber is tougher carbon, with unique materials and layup procedures, Trek's advanced engineering, and a higher standard of testing.
Straight Shot downtube
Straight Shot downtube gives you an extra-stiff frame without adding any weight, so you can stick your line through the rough stuff and still fly up the next climb.
Knock Block has your frame's back when things go wrong. It prevents your handlebars from spinning all the way around in a crash, so your hoses won't get yanked, and your controls won't hit the top tube.
Complete Tubeless System
Tubeless Ready rims and tires make it easy to ditch the tubes so you get better traction, fewer flats, and less weight. You're ready to roll right out of the box with the included TLR rim strips, valves, and sealant.

Easier internal routing
Integrated channels in the frame make it super easy to route cable housing and brake hose so you get a clean set-up with no hassle.

Sizing & Tech
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 retailer.
