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 SRAM NX Eagle 1x12 drivetrain, and Shimano hydraulic disc brakes. Plus, Bontrager Kovee 28-hole Tubeless Ready wheels and an adjustable RockShox Judy Gold RL air fork with 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 precise hydraulic disc brakes, Procaliber 6 gives you a fast, efficient ride that can't be matched for this price.

IsoSpeed decoupler
Our innovative decoupler allows the seat tube to rotate independently from the top-tube-to-seatstay junction, increasing vertical compliance without compromising pedaling efficiency.
Learn more
Remote lockout
Handlebar-mounted controls let you lock out your suspension on the fly as you switch terrains.
Internal derailleur routing
Sleek ports at the head tube and near the seat tube let you route your derailleur cables through the frame to keep your bike running smooth and clean.
Smart Wheel Size
The right wheel size paired with your frame size gives you the perfect combination of responsiveness and control.
Boost148/110
Wider dropouts (110mm front, 148mm rear) give you the stiffness of a 27.5" wheel with all the benefits of a 29" wheel, and Boost148 in the rear lets you run wider tires and a larger chainring without affecting q-factor and pedaling efficiency.
G2 Geometry
Advanced frame geometry and a custom offset fork give our 29ers precise handling at low speed without compromising high-speed stability. We call it G2 Geometry, and it's why our 29ers handle better than anyone's.
Extended size range
A wider range of sizes than the industry standard provides more option for everyone, from tallest to shortest and all those in between. Because everyone deserves a great ride.
Alpha Platinum Aluminum
Our premium lightweight aluminum is continuously cold extruded and butted at multiple points, and hydroformed into sophisticated tube shapes for maximum strength and minimum weight.
