DT Swiss ARC 1100 Dicut Disc Brake 50 Wheelset Shimano

The latest generation of ARC 1100 DICUT wheels was developed in cooperation with SWISS SIDE, leading expert in aerodynamic optimization. Consequently, the new AERO+ rim profile minimizes both aero drag and steering moment to improve its aerodynamic and controlling in even strong cross wind. Thus, it makes it easier for the rider to keep the aero wheel under control while taking advantage of the forward-pushing sailing effect. The wheel setup is completed by the new DT Swiss aero spokes in combination with the sleek 180 DICUT hub including ultra-light running SINC ceramic bearings.

FEATURES:

Translational Drag - 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.

Quintessence of Drag - Considering the front wheel, which is more susceptible to wind, different effects are observed in different wind conditions. The illustration depicts a model curve which shows the behavior of the front wheel in wind. While the X-axis indicates the angle from which the air flows onto the moving front wheel (yaw), the Y-axis represents drag values (watt).

Rotational Drag - In addition to moving at a certain speed facing translational drag, the rotating parts of the bike such as the wheels are also affected by rotational drag. Rotational drag can be described as the additional friction that occurs between the wheel as it passes through the surrounding air with rotating components.

Steering Moment - Lateral forces come into contact with the wheel and can influence rideability. Handling therefore needs to be safe and predictable, regardless of external weather conditions such as strong and changing crosswind and headwind. To achieve controlled speed, the AERO+ rim is further refined in this respect with lower steering moment. The cyclist benefits from more predictable, and thus controlled, steering behavior, resulting in longer periods in the aerodynamically optimal position and higher speeds.

Rolling Resistance - Rolling resistance is about more than just the forces which are applied to roll on different surfaces or overcome obstacles. Wider rim inner widths and wider tires support efficiency and riding characteristics such as traction and comfort.
