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 mixed SRAM SX and NX Eagle 1x12 drivetrain, and Shimano hydraulic disc brakes. Plus, Bontrager Kovee 28-hole Tubeless Ready wheels and an adjustable RockShox Judy Gold air fork with Motion Control damper and remote lockout that lets you lock out the fork without taking your hands off the bars.
The final word
A lightweight cross-country ride with advanced IsoSpeed tech that just isn't available anywhere else. With a 1x12 drivetrain, the trail-smoothing IsoSpeed decoupler, and powerful hydraulic disc brakes, Procaliber 6 gives you a fast, efficient ride that can't be matched for this price.

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.
