2017 Jamis DXT Comp
Go anywhere. Do anything.
The drivetrains on our DXT bikes feature long cage ATB rear derailleurs, full size triple chainring cranksets and big 11-34 or 32T cassette blocks. This gives you the dual advantage of having high road bike gearing for controlled pedaling at speed on descents and low mountain bike gearing for easier pedaling uphill.
Every DXT offers a full complement of eyelets and rack mounts to simplify installation of carriers and fenders. We even include bosses on the underside of the seatstays for installation of a ring lock. Ring locks are tremendously popular in Europe. A simple turn of the key immobilizes the rear wheel and prevents someone from riding off with your bike.
Adjustable Cockpit Height
Proper fit on your bike is critical for maximum performance and comfort. That's why we offer the ATS patented adjustable threadless steering system on the DXT Elite models. Whether you want to fine tune your ride and establish the perfect fit. or change it regularly to suit different terrain, with this stem, adjusting handlebar height is as easy as adjusting your seat post height.
Suspension when you need it, lockout when you dont
The advantage of a suspension for should be intuitively clear; hit a bump and absorb it. Hot a bump and stay in control of your bike. But suspension isn't always desirable. When riding on smooth pavement or climbing, pedaling energy and power can be absorbed and dissipated by the movement, allowing the bike to be 100% responsive to pedaling input.
Giving you a Brake
The advantages of disc brake over rim brakes on a versatile bike like the DXT far exceed their sole disadvantage, weight gain. Besides their incredible power and modulation, their just plain safer, especially in the rain. Once the rims get wet or muddy, using friction to stop the wheel at its circumference is less efficient than using friction to stop a less wet or muddy small diameter disc near the center of the wheel from rotating. And elimination the rim from braking surface duties results in a longer lasting wheel.
Full Shimano Shifting System
Fully integrated shifting systems offer the most precise and reliable performance. That's why every DXT offers Shimano shifters, SHimano front and rear derailleurs, Shimano crankset and Shimano cassettes
The advantage of large diameter wheels is getting a lot of press these days with all th enoise and news about 29'er mountain bikes. We like to think that the DXT is one of the original 29'ers. with big 700c hoops (same ad 29'ers) that roll over bumps and holes better than small diameter 26" or 27.5" wheels, and with a bigger contact patch for greater traction and control. But in the case of the DXT, with a smaller 40c width and smoother tread that significantly reduces rolling resistance over fatter, knobbier mountain bike tires for faster sailing on streets and paths.
