Trek's X-Caliber is the way to jump headlong into the world of mountain biking. It sports Trek's nimble Gold Series aluminum frame and a plush 75mm-travel Suntour suspension fork for a light, lively ride and confidence over rocks, roots, potholes-you name it. And that confidence is only helped by the big 29-inch wheels and knobby tires. You'll enjoy easy pedaling and complete control thanks to the quick-shifting 24-speed drivetrain and sure-stopping mechanical-disc brakes. Plus, you'll love the comfy Bontrager seat.
