Dt Swiss ARC 1100 Dicut 55 DB WTS 2025 Wheels

Being a leader is not for the faint-hearted. The third generation of ARC reaches a new level of innovation: greater internal rim width, now 22 mm ideal for wider tires, and better grip and comfort. You will be able to pedal faster, longer. Three different rim heights, 55, 65, 85 mm, with a V-shape section that allows a wider internal channel without compromising aerodynamics or weight. With a 38 mm high rim, the perfect combination of great lightness and aerodynamic optimization, the ARC 1100 DICUT 38 remain the ultimate climbing wheels. The top-of-the-line 180 DICUT hub with Ratchet EXP system, SINC ceramic bearings, and DT Aerolite II spokes are the ultimate essential ingredients to cross the finish line first. Join our mission to improve, give your best, and always stay one step ahead. Leadership is not given as a gift, it is earned. Conquer the top of the general classification: these wheels offer excellent aerodynamic performance and great handling. And thanks to their reduced weight, they are ready to tackle even the toughest climbs.

Greater internal rim width
The rim's 22 mm internal width is ideal for fitting wider tires (28 to 30 mm) for greater comfort.

Carbon Rim with V shape
The new rim shape develops a smaller frontal area resulting in reduced aerodynamic drag.

Aero WTS
Now available as a complete aerodynamic wheel system (WTS) with new front tire AERO 111.

Aero Spokes
Our latest generation spokes, the DT Aerolite II, guarantee low aerodynamic resistance to rotation and translation.

Hub
New 180 DICUT hubs with low-friction SINC Ceramic bearings.

Technologies

WTS technology
Optimization of wheel and tire as a complete system to be even faster. While already offering some of the fastest wheels on the market, the next step was to start considering wheel and tire as a complete system: the Wheel Tire System (WTS). With AERO 111, we developed the ideal front tire tailored to our rims, taking aerodynamic optimization to the next level.

Aero+
The perfect symbiosis of strength, handling, and efficiency. Translational resistance is the aerodynamic force that slows the cyclist in the direction of travel. This force depends on the frontal impact surface of the cyclist (75%), the road bike and its components (25%), as well as speed. To minimize translational resistance, the impact surface of the cyclist/bike combination must be limited, optimizing its aerodynamics as much as possible.

SINC ceramic technology
These ball bearings were developed by DT Swiss to minimize rolling resistance. The balls are made of silicon nitride (Si3N4), an extremely hard ceramic material resistant to wear and corrosion. Combined with steel alloy rings, the hardened ceramic balls ensure smoother operation over time and faster break-in compared to conventional steel bearings.
At DT Swiss, we believe that details make the difference. And the SINC ceramic ball bearings are based precisely on attention to the smallest details.

Combined with steel alloy rings, the hardened ceramic balls ensure smoother operation over time and faster break-in compared to conventional steel bearings.

Tubeless technology
All DT Swiss wheels are compatible with tubeless technology, and the ASM versions are prepared for the tubeless system, equipped with tubeless tape and valves.
