Tackle the heights of joy!

Experience joy at new heights with this road cycling wheel. From conquering local hills to exploring alpine passes, it is developed for all altitudes. With our reliable Ratchet LN technology, you will enjoy seamless power transfer on even the steepest climbs. Hand-built for even spoke tension, you can rely on the wheel on the longest descents.

Rim
The new rim offers a great combination of width and lightness to ensure a comfortable ride both uphill and downhill.
 
Spokes
The DT new aero® II straightpull will let you ride with confidence and ease thanks to their reinforced and aero construction.

Hub
The upgrade of the 370 hub to the Ratchet LN system brings in an increased reliability, and its signature freewheeling sounds.

Freehub body
The higher reliability of the Ratchet LN system is achieved by the simultaneous engagement of each tooth in comparison to the pawl system and its smaller engagement surfaces.

Technologies

Ratchet
Every ratchet has its purpose. Learn more about the different DT Swiss freehub systems. Each Ratchet System has its special characteristics, but they all provide the iconic reliability. This is a result of the simultaneous engagement of the teeth, creating far fewer point loads. Discover how the constructions differ and which common features they share.

Tubeless
All DT Swiss wheelsets are tubeless compatible and the ASM versions come tubeless ready, equipped with tubeless tape and valves. 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.

Bearing
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. In order for a bearing to rotate, there must be a certain amount of play in the thousandth of a millimeter range. Without this clearance, the bearing cannot rotate. Bearing play occurs both radially and axially. Axial clearance describes how far one bearing ring can be displaced longitudinally relative to the other without load. Radial clearance is measured vertically to the center axis of the bearing.

Spokes
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.
