Procaliber 6 is a fast cross country mountain bike and the most affordable MTB model with IsoSpeed—a decoupler at the top tube/seat tube junction that provides additional compliance on rough courses. IsoSpeed gives you a unique and substantial advantage over a traditional hardtail, because it cuts down on the trail's fatiguing bumps and delivers a smoother, faster ride.

It's right for you if...

You like to go fast, and also love the idea of a hardtail with frame tech designed to take the edge off rough singletrack. Speed is your main consideration, but comfort is right up there, too.

The tech you get

A durable and light Alpha Platinum Aluminum frame with IsoSpeed, a Shimano Deore XT/SLX 2x11 drivetrain, and Shimano hydraulic disc brakes. Plus, Bontrager Duster Elite Tubeless Ready Wheels and an adjustable RockShox Recon Gold RL air fork with remote lockout that lets you lock out the fork without taking your hands off the bars.

The final word

You're getting great spec, but what you're really buying is a lightweight frame with advanced IsoSpeed tech, which just isn't available anywhere else. With quality components, the trail-smoothing IsoSpeed decoupler, and precise hydraulic disc brakes, Procaliber 6 gives you a fast, efficient ride that can't be matched for this price.

favorite_borderWhy you'll love it

  1. IsoSpeed is a real advantage, and you can't find it in any other hardtail family
  2. It's a great bike for someone who's just getting into serious racing—you get high-end XC parts on an awesome frame with enough cash left over for entry fees
  3. The sleek internal cable routing gives you clean looks and protects your cables
  4. There's nothing as sweet as a silent ride: the clutch rear derailleur prevents chain slap, even in the rough

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.
