DT Swiss Arc 1100 Dicut 38 Disc wheelset

The ultimate climbing wheelset combining light weight and aero-optimization for a swift rise to the top

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.

Technologies

Aero+
The symbiosis of drag, handling and efficiency. When refining a wheel according to AERO+, the optimization of all parameters is subject to one single goal: higher speeds!

Ratchet EXP
The hubs are known for their no tool technology. DT Swiss found a way to further improve this system and make maintenance even simpler, by a small change of the end caps. Not only the reliability improved. The fusion of ratchet and threaded ring reduces the number of single parts of the system, which offers an important advantage. A single cylindrical spring ensures faster full engagement and thus increases reliability. The full engagement of the ratchets creates a large contact surface and therefore low surface pressure that leads to superior reliability. The integration of the bearing into the threaded ring allows the bearing distance to be maximized. The increased distance further supports the axis, which results in less deflection of the axle and thus protects the bearings and increases their lifetime.

Sinc Ceramic Technology
At DT Swiss we believe that the difference is in the detail. SINC ceramic ball bearings are precisely based on such details. Thanks to the optimization of these details, a DT Swiss wheel with a SINC upgrade simply means that you will be ahead of the field, your friends or setting new personal bests. Is installed in all DT Swiss 1100 wheels. The rider benefits from a reduced rolling resistance and extended durability.

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 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. Learn how to ensure the optimal rotating property of the ball bearings and discover why DT Swiss does not offer hubs with adjustable bearing clearance. In order for a bearing to rotate, there must be a certain amount of play in the thousandth of a millimeter range. Without this clearance, the bearing cannot rotate. Bearing play occurs both radially and axially. Axial clearance describes how far one bearing ring can be displaced longitudinally relative to the other without load. Radial clearance is measured vertically to the center axis of the bearing.
