DT Swiss ARC 1400 Dicut Disc Brake 50mm Wheelset Shimano

DT Swiss ARC Aero 2nd Generation – Faster Than Ever

Reborn Faster – DT Swiss introduces the second generation of its ARC Aero wheels, designed for the dominance of disc brakes and the growing trend of wider, tubeless tires. Developed with aerodynamics experts from Swiss Side, these wheels balance speed, stability, and control using the AERO+ concept.

Optimized Rim Shape for Speed & Stability

With disc brakes allowing more design freedom, the new ARC wheels feature a wider rim profile, blending V and U shapes for better aerodynamics. The 20mm inner width supports 25mm and 28mm tires, reducing rolling resistance and improving comfort. Wind tunnel tests confirm top performance in all wind conditions, with improved crosswind stability for better handling and fewer steering corrections.

DICUT 240 Hubs – Lighter, Stiffer, More Efficient

At the core of these wheels are DT Swiss 240 DICUT hubs with EXP technology, offering weight reduction, increased stiffness, and improved aerodynamics. The Ratchet EXP system provides precise, reliable power transfer with 36 engagement points. With durable seals and optimized bearing sizes, these hubs require minimal maintenance and deliver maximum efficiency.

Faster, more stable, and built for modern performance – the ARC Aero 2nd Gen is designed to push the limits of speed and control.
