DT Swiss ARC 1100 DICUT DB
- The latest generation of ARC 1100 DICUT wheels – available in disc brake version in three different rim heights 80 mm, 62 mm and 50 mm – 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.
ARC 1100 DICUT 80: The sophisticated wheelset in the quest for best times on flat to slightly undulating courses.
ARC 1100 DICUT 62: The all-round aero wheelset with excellent performance for various riding fields.
ARC 1100 DICUT 50: The most agile and fast accelerating wheelset for hilly or flat courses with sharp turns.
THE HIGHEST QUALITY OF BEARING TECHNOLOGY is installed in all DT Swiss 1100 wheels. The rider benefits from a reduced rolling resistance and extended durability. SINC ceramic ball bearings have been developed by DT Swiss as a system. They are based on balls made from silicon nitride (Si3N4), an extremely tough and wear- and corrosion-resistant ceramic material. The bearing rings are made from a specially developed steel alloy, which is adapted to the properties of the specific ceramic material used and are precision ground. This combination reduces the rolling resistance to an absolute minimum and guarantees greater durability than conventional ball bearings. But it is not just the bearing itself that is conceived as a system. It's only by using tolerances within a few thousandths of a millimeter and precisely tuning the tolerances of DT Swiss hub bearing seats that SINC ceramic bearings deliver their full potential and offer the decisive advantage over competing products.
LEGENDARY RELIABILTY The patented freewheel system, which features high-precision star ratchets, guarantees top performance and reliability. The simultaneous engagement of the ratchet teeth makes the Ratchet System extremely reliable since the loads are distributed equally across a large contact surface.
PRO LOCK TECHNOLOGY Pro Lock® is a process where a patented, dual compound, adhesive liquid is injected into the nipple thread, allowing for extremely durable wheel builds. By threading the nipple onto the spoke the adhesive is activated and starts to harden. Re-truing the wheel is still possible after the adhesive has hardened completely, with only a minimal decrease of its thread-lock function.
BEARING TECHNOLOGY 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. HUB CONSTRUCTION DT Swiss hubs are engineered to have the optimum axial and radial bearing clearance when the hubs are properly installed in the wheel and bike. To achieve this, it is important to assemble the hub in the correct order. To start, the first bearing is pressed into the hub shell so that it sits flush with both the shell and the axle. The second bearing is then pressed in so it sits flush with the axle, but not with the hub shell. Therefore the axle is minimally compressed. The bearing sits at a press-fit, in which the outer bearing ring can no longer move relative to the hub shell.
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 for long and far away from the next bikeshop.
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. If you want to be faster, the key is to reduce the aerodynamic drag of the complete system of road bike and cyclist as the force increases exponentially. From 15 km/h upwards, aerodynamic drag is the greatest resistance a cyclist has to overcome. As the front wheel contributes 8 % of total drag, the wheel’s behavior plays a significant role.
