Description

When you´re fully committed to having fun and not always riding the planned lines, the EX 1700 CLASSIC is ready to get rowdy. The 350 DEG DF will almost cancel out pedal kickback, diminishing the noise from the rough. Asymmetric aluminum rims are laced with DT competition race spokes, with 28 in the front and a burly 32 in the back. For enduro riders looking to reach the podium, the EX 1700 CLASSIC is all about fun and no fuss, and ready to get rowdy.
Rim:
– The aim is to strike the perfect balance between agility and durability. The front rim is lighter with 28 spoke holes, while the rear rim, with 32 spoke holes, is stronger. Both rims are asymmetrically welded.
Spokes:
– The DT competition race spokes and their extra thin middle section saves weight for an almost equal stiffness and durability.
Hubs:
– The 350 DEG hub, with its 72 points of engagement, ensure a reliable acceleration, to negociate the trickiest sections with confidence. While the CLASSIC hubshell ensures more durability.
Anti pedal-kickback technology:
– The DF technology adds a radically simplified anti-pedal kickback system. The tool-free adjustment (0, 10, or 20 degrees of freedom) ensures that you can find the right setup for your riding style, guaranteeing fun for all.

Technology:
Ratchet System:
– The Ratchet System is the first of this type of freehub system for DT Swiss. This patented freewheel system, which features high-precision star ratchets, guarantees top performance and reliability.
DF:
– The new DF technology is an anti-pedal kickback device simplified to the max. The DF technology releases the pedal kickback at the point where it occurs: in the freehub. This prevents unwanted chain pull during compression before it reaches the crank via the chain and negatively affects the rider. This results in improved downhill riding behavior with natural feedback from the trail and bike without the influence of unwanted chain pull.
Bearing Technology:
– DT Swiss hubs are designed to function optimally once installed in a bicycle. To achieve this, the clamping force created by the wheel mounting system must be taken into account when constructing a hub. Learn how to ensure the optimal rotating property of the ball bearings and discover why DT Swiss does not offer hubs with adjustable bearing clearance.
Spoke Technology:
– The production of high-quality spokes marked the beginning of the company. DT was synonymous with top quality Swiss spokes, even before the establishment of today‘s DT Swiss AG. To this day, DT Swiss spokes stand for durability and precision and are unrivalled thanks to their unique production process that combines lightweight with durability.
Tubeless:
– Tubeless tires have a number of advantages over the conventional combination of tube and tire: without risking snakebites, the tire can be run with lower pressures providing better grip. The lower pressure also results in a more comfortable ride. Eliminating the tube means there is no friction between tube and tire and therefore less rolling resistance when the tire rolls over the ground and obstacles. If tubeless sealant is used, the tire can self-seal stings and small cuts. A big advantage for all those who like to ride long and far from the next bikeshop.
