DT Swiss ARC 1100 DiCut 38 Rear Wheel – 700 12 x 142mm Center-Lock HG 11 Road 3 Decades. The latest generation of ARC 1100 DiCut wheels were developed in cooperation with Swiss Side a 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.
