Description
DT SWISS front wheel ARC 1100 DICUT Disc Brake Carbon Clincher 50 mm
Reborn Faster - this is the slogan under which DT-Swiss launches the 2nd generation of their ARC Aero wheel series. With the new dominance of disc brakes on the market and the trend towards wider, tubeless tires, the starting point for the development of road bike wheels has changed significantly. When developing the wheels, DT-Swiss stuck to their AERO+ concept, which aims to balance sometimes conflicting requirements such as maximum speed and the best possible handling. The close cooperation with the aerodynamics experts from Swiss Side has also remained, who, in addition to 20 years of experience from Formula 1, have also been able to convince with first-class cycling innovations in the recent past.
New rim shape
With the greater freedom provided by the disc brake system, the rim shape of the ARC wheels could be made wider. While the previous profile resembled the widespread U-shape, the new profile is a combination of the classic V and U shapes. At 20 millimeters, the inner width has increased significantly in order to be able to integrate 25 and 28 millimeter wide tires in an aerodynamic manner and to be able to use the rolling resistance and comfort advantages of the wider tires. In a direct comparison in the wind tunnel, the impellers were able to achieve top values in all relevant inflow angles. However, thanks to the AERO+ concept, the new rims are not only fast, their susceptibility to crosswinds has also been improved. This allows the rider to stay in an aerodynamic seating position for longer and to make fewer steering corrections in strong winds.
Newly developed spokes
Even during the development of the first generation of ARC wheels, DT Swiss recognized great potential in optimizing rotational air resistance. This knowledge was taken into account with the development of the new Aerolite II and Aero Comp II spokes. Compared to the previous version, the Aerolite II is 35% wider and 23% thinner. Due to the flat forging process of the spokes, the steel is compressed more, which leads to a higher tensile strength. In addition, the aerodynamically optimized Straightpull T-Head suspension of the spokes and internal nipples ensure less rotational and translational resistance.
DICUT 180 hubs
The latest generation of the 180 DICUT hubs with DT Swiss EXP technology rotates in the center of the wheels. Equipped with high-quality SINC ceramic bearings, they help to save a few watts. In addition to a weight reduction compared to the previous version, the hubs have also become stiffer and offer aerodynamically optimized straight pull hub flanges and hub bodies. Thanks to the use of complex seals and bearing sizes adapted to the loads, the hubs do not need to adjust the bearing play.
