It's right for you if...
You're more than a casual singletrack rider. You put in long miles on the trail, show up to race, and want the speed, efficiency, and light weight of a carbon cross country bike with IsoSpeed.
The tech you get
A light and stiff carbon frame with the unique advantage of our trail-smoothing IsoSpeed, a 100mm RockShox Recon Gold RL fork with a plush DebonAir spring and remote lockout, a lighter-weight wide-range Shimano SLX drivetrain, and tubeless 29" Bontrager Kovee Comp 23 wheels.
The final word
This bike can compete with the very best hardtails out there. You get fatigue-fighting IsoSpeed with component upgrades that save weight and give you better handling. If you want to rock the local race scene and rack up serious mileage, Procaliber 9.6 is a great choice.
The Walkthrough
favorite_borderWhy you'll love it
- The upgraded fork gives you a remote lockout, a more plush spring, and a damper that gives you more control over the rough stuff.
- 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
- The solid XC groupset will hold its own on the race course, but it's also going to hang tough through everyday training rides
- 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 remote lockout lets you lock out the fork without taking your hands off the bars

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.
