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 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. Why you'll love it - The IsoSpeed decoupler makes it ride smoother than any other hardtail, so your body doesn't get beat up by trail chatter - 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 - Internal cable routing extends the life of your cables and adds to the bike's sleek look - The 1x12 drivetrain gives you a super wide range of gears in a simple setup
