Dt Swiss Arc 1400 Dicut 38 DB wheelset 2024

The ideal climbing wheelset for blasting through the iconic climbs on your bucket list

The sophisticated ARC 1400 DICUT wheels represent the latest DNA of the 1400 level of DT Swiss and SWISS SIDE. Available in disc brake version, the AERO+ profile rims set a new standard in aerodynamic performance and keep aero drag as low as possible under different crosswind angles. In moderate side wind conditions, riders benefit from propulsion through a sailing effect. Reduced wind sensitivity allows riders to maintain a stable aerodynamic position and full control of their bike. High-end DT Swiss aero spokes and the light 240 DICUT hub with its reliable Ratchet EXP system for more direct engagement complete this wheelsets.

Wheel Tire System
Now available as an aero-optimized wheel tire system (WTS) mounted with the new AERO 111 tire in the front.

Hub
Precise engagement by the Ratchet EXP freehub technology.

Spokes
Patented T-heads ensure a perfect aerodynamic alignment of DT aero comp spokes.

Technologies

Aero+
The symbiosis of drag, handling and efficiency. Translational drag is the aerodynamic force in the riding direction that slows the cyclist down. It consists of the frontal area of the cyclist (75 %), the road bike and its components (25 %), and speed. To minimize this translational drag, the surface of the overall system needs to be minimized while streamlining the entire road bike and cyclist as far as possible. Sailing effect In crosswind conditions, the cyclist and road bike are exposed to lateral forces that affect riding behavior. When developing wheels for road bikes, the aim is to minimize these lateral forces and maximize the sailing effect – combined with best rideability. The sailing effect of the wheels can be compared to a sailboat whose sail catches the wind and propels the boat. When cycling, the rim has the same effect and can push the whole system forward. Thus, in moderate crosswind conditions with an inflow of between 0°-20° yaw, the cyclist is no longer slowed down by translational drag but benefits from drag reduction with increasing yaw angle. Depending on the rim height and shape, this drag reduction can reach negative watt values which even create forward propulsion. Excellent sailing effects with crosswind occur with yaw angles up to 18°. Beyond that, stall occurs that causes drag to increase again.

Tubeless technology
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.
