Procaliber 9.7 - Trek Bikes (CA)

Overview

You're a trail veteran and a regular at your local XC races. You want parts upgrades that make you faster, like lighter carbon wheels and a wider-range drivetrain that saves your legs on the steepest climbs.

A light and stiff carbon frame with trail-smoothing IsoSpeed, a lighter RockShox Reba RL fork with a Solo Air spring, Motion Control damper and a remote lockout, an extra-wide-range SRAM GX Eagle drivetrain, fast 29" Bontrager Kovee Elite 23 carbon wheels and a carbon seatpost.

An awesome bike for serious racers. The upgraded fork and carbon wheels give you big weight savings for a faster ride.

Carbon frame, carbon wheels, and carbon seatpost spec'd for a lightweight performance ride
The IsoSpeed decoupler makes it ride smoother than any other hardtail, so your body doesn't get beat up by trail chatter
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
Carbon rims save rolling weight so you can go faster with less effort
The new SRAM GX Eagle drivetrain gives you an extra-low climbing gear that saves energy over the long haul

"Faster with less fatigue than any other XC hardtail in test...Procaliber was still the smoothest bike here."

Procaliber offers a more comfortable ride than a traditional hardtail. It's noticeable right away. Ready to go uphill and down with no regard for anything except stopping to get on the podum.

Features

IsoSpeed takes the edge off body-beating small bumps and trail chatter so you can stay stronger longer, without giving up any pedaling efficiency.

Trek's mountain-specific carbon fiber is tougher carbon, with unique materials and layup procedures, Trek's advanced engineering, and a higher standard of testing.

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 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.

Tubeless Ready rims and tires make it easy to ditch the tubes so you get better traction, fewer flats, and less weight. You're ready to roll right out of the box with the included TLR rim strips, valves, and sealant.
