DT SWISS rear wheel ARC 1100 DICUT Disc Brake Carbon Clincher 50 mm
Reborn Faster - this is the slogan under which DT-Swiss is launching the 2nd generation of its 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 its AERO+ concept, which aims to balance sometimes contradictory requirements such as maximum speed and the best possible handling. The close cooperation with the aerodynamics experts from Swiss Side has also continued, who, in addition to 20 years of experience from Formula 1, have also been able to impress with first-class cycling innovations in the recent past.
New rim shape
With the greater clearance provided by the disc brake system, the rim shape of the ARC wheels could be made wider. While the previous profile resembled the widely used U-shape, the new profile is a combination of the classic V- and U-shape. At 20 millimetres, the inner width has increased significantly in order to integrate 25 and 28 millimetre wide tires in an aerodynamically favourable way 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 wheels achieved top values in all relevant angles of attack. Thanks to the AERO+ concept, the new rims are not only fast, but crosswind susceptibility has also been improved. This allows the rider to remain in an aerodynamic riding position for longer and to have to make fewer steering corrections in strong winds.
Newly developed spokes
Already during the development of the first generation of ARC wheels, DT Swiss recognized great potential in the optimization of rotational drag. With the development of the new Aerolite II and Aero Comp II spokes, this realization was taken into account. Compared to the previous version, the Aerolite II is now 35% wider and 23% thinner. Due to the flat forging process of the spokes, the steel is more compressed, which leads to a higher tensile strength. In addition, the aerodynamically optimized straight-pull T-head suspension of the spokes and internal nipples ensure less rotational and translational resistance.
DICUT 180 hubs
At the center of the wheels is the latest generation of 180 DICUT hubs with DT Swiss EXP technology. Equipped with high-quality SINC ceramic bearings, they help to save a watt or two. In addition to a weight reduction compared to the previous version, the hubs have also become stiffer and offer aerodynamically optimized straightpull hub flanges and hub bodies. Thanks to the use of elaborate seals and bearing sizes adapted to the loads, the hubs do not require any adjustment of the bearing play. The Ratchet-EXP toothed pulley freehub system with its large contact surface and 36 engagement points ensures extremely direct and reliable power transmission.
Note:
A Center Lock lockring with external teeth is required for correct brake rotor installation. DT Swiss recommends the SM-HB20 from Shimano.
