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, powerful Shimano hydraulic disc brakes, 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 parts 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..

favorite_borderWhy you'll love it

  1. The upgraded fork gives you a remote lockout, a more plush spring, and a damper that gives you more control over the rough stuff.
  2. 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
  3. The solid XC parts group will hold its own on the race course, but it's also going to hold up through everyday training rides
  4. 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
  5. The remote lockout lets you lock out the fork without taking your hands off the bars

Straight Shot downtube

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

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.

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.
