Jamis DXT A2 Step-Through

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

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.

Drivetrain-wise you get a Shimano 2×8 (16-speed) setup: Altus RapidFire shifters, Acera rear derailleur, TY710 front, an 11–34T cassette and a 46/30T crank. That range covers short, steep climbs without spinning out on flats. Alex TD26 double-wall rims (36h) with alloy disc hubs add everyday durability, while contact points are chosen for comfort—an ergo grip set, micro-adjust seatpost and Jamis Touring saddle.
