Jamis DXT A2 Step-Thru
The dual-sport DXT’s are pumped-up, go-anywhere/do-anything versions of our Allegro fitness bikes. With more gearing range to take on steeper hills and tougher terrain. Wider tires with a trail-capable tread for access to more riding areas, both paved and packed. And disc brakes and suspension forks for real off-road exploration and off-pavement adventure
Absolute Versatility - 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.
Full Shimano Shifting System - Fully integrated shifting systems offer the most precise and reliable performance. Thats why every DXT offers Shimano shifters, Shimano front and rear derailleurs, Shimano cassettes. Even Shimano cranksets on all models except the DXT.
Suspension When You Need It, Lockout When You Dont - 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 isnt 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 forks 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, theyre 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
Fast Rollers - The advantage of large diameter wheels is getting a lot of press these days with all the noise and news about 29er mountain bikes. We like to think that the DXT is one of the original 29ers. With big 700c hoops (same as a 29er) 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 42c width & smoother tread that significantly reduces rolling resistance over fatter, knobbier mountain bike tires for faster sailing on streets and paths.
