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 all DXT 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 your handlebar height is as easy as adjusting your seat post height.
Suspension When You Need It, Lockout When You Don?t
The advantage of a suspension fork should be intuitively clear: hit a bump and absorb it. Hit 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 (bobbing) of the fork. Enter lockout. With a flip of a knob on the top of the fork, the fork?s travel can be locked from movement, allowing the bike to be 100% responsive to pedaling input.
Giving You a Brake
The advantages of disc brakes over rim brakes on a versatile bike like the DXT far exceed their sole disadvantage, weight gain. Besides their incredible power and modulation, they?re just plain safer, especially in the rain. Once 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 eliminating 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 cranksets and Shimano cassettes.
The advantage of large diameter wheels is getting a lot of press these days with all the noise 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 as a 29?er) that roll over bumps & holes better than smaller 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 & smoother tread that significantly reduces rolling resistance over fatter, knobbier mountain bike tires for faster sailing on streets and paths.
UPGRADES FROM DXT SPORT
- Shimano FC-M311 crankset
- Shimano Rapidfire SL-M310 shifters
- Shimano Altus RD-M310 SGS rear and FD-M191 front derailleurs
- Tektro HD-M290 hydraulic disc brakes
TOP FIVE THINGS YOU NEED TO KNOW
SR/Suntour?s SF15-NVX HLO suspension fork offers 75mm of travel, hydraulic damping for a smoother ride and hydraulic lockout to prevent front-end bobbing during climbing.
Tektro’s HD-M290 dual piston hydraulic disc brakes offer more power, better modulation & feel, require less maintenance and are often lighter than many cable-actuated disc brakes.
A Shimano drivetrain ensures the quickest, most reliable shifts every time, all the time. The 24-speed Rapidfire shifting drivetrain with Shimano M311 48/38/28 crankset, Acera/Deore derailleurs and 11-32t cassette offers a much larger gear range, with much lower gearing, for easier hill climbing than standard or compact double chainring road and street bikes.
Ritchey’s Speedmax Cross tire offers a large footprint with both a fast, low rolling resistance center patch as well as side knobs for consistent traction at all cornering angles.
Our ATS adjustable-height steering system is much lighter than traditional angle adjustable stems, and offers a much faster and easier method for adjusting handlebar height for more efficient and comfortable riding.
