Dt Swiss ARC 1100 Dicut 55 DB WTS Wheels 2025

Being a leader is not for the faint-hearted. The third generation of ARC reaches a new level of innovation: a wider internal rim width, now 22 mm, ideal for wider tyres, and improved grip and comfort. This lets you ride faster for longer. Three different rim depths, 55, 65, 85 mm, with a V-shaped profile that allows a wider internal channel without compromising aerodynamics or weight. With a rim depth of 38 mm, the perfect combination of low weight and aerodynamic optimisation, the ARC 1100 DICUT 38 remain the ultimate climbing wheels. The top-of-the-range 180 DICUT hub with Ratchet EXP system, SINC ceramic bearings and DT Aerolite II spokes are the essential ingredients for crossing the finish line first. Join our mission to improve, give our all and always stay one step ahead. Leadership is earned, not given. Take the lead in the general classification: these wheels offer excellent aerodynamic performance and great handling. And thanks to their low weight, they are ready to tackle even the toughest climbs.

Wider internal rim width
The internal rim width of 22 mm is ideal for fitting wide tyres (from 28 to 30 mm) for greater comfort.

V-shaped carbon rim
The new rim shape has a smaller frontal area, resulting in reduced aerodynamic drag.

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

Aero spokes
Our latest-generation spokes, the DT Aerolite II, ensure low rotational and translational aerodynamic drag.

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

Technologies

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

Aero+
The perfect symbiosis of drag, handling and efficiency. Translational drag is the aerodynamic force that slows the rider in the direction of travel. This force depends on the frontal area of the rider (75%), the road bike and its components (25%), as well as speed. To minimise translational drag, the frontal area of the rider/bike combination must be reduced, optimising its aerodynamics as much as possible.

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

Tubeless technology
All DT Swiss wheels are compatible with tubeless technology, and the ASM versions are tubeless-ready, equipped with tubeless tape and valves.
