DT Swiss ARC 1100 Dicut DB 50 Carbon Disc Tubeless Ready Wheels

ARC 1100 Dicut DB - The most advanced wheels from DT Swiss for safe bike handling at any time

The latest generation of ARC 1100 DICUT wheels was developed in collaboration with SWISS SIDE, an expert leader in aerodynamic optimization. As a result, the new AERO+ rim profile minimizes both aerodynamic drag and steering moment to improve aerodynamics and control even in strong lateral vento . This makes it easier for the rider to keep the wheel under control while also taking advantage of the pushing effect. The wheel configuration is rounded off by the new aerodynamic spokes DT Swiss in combination with the elegant 180 DICUT hub with ultra-light SINC ceramic bearings.

Technologies

Tubeless
Tubeless Ready rims from the DT Swiss range offer additional advantages over traditional rims. Their cross-sectional design allows the tire to heel more easily when inflating, even with a standard floor pump. The elaborate DT Swiss rim profile also ensures precise and safe fit of the tyre even during aggressive driving.

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

• Translational drag: Aerodynamic drag is the aerodynamic force in the direction of travel that slows down the rider. If you want to be faster, the key is to reduce the drag of the entire system.
• Sail effect: In lateral vento conditions, the cyclist and la bici are exposed to lateral forces that affect riding behavior. When developing wheels for road bikes, the goal is to minimize these lateral forces and maximize the sailing effect - in combination with the best rideability.
• Quintessence of aerodynamic drag: In conditions of contrary vento and slight lateral vento , the rider is slowed down by aerodynamic drag. The watt values are positive (above the red line at +/-14° yaw) and the aerodynamic drag is perceived as exhausting. However, the sideways vento combined with high rim profiles support the rider in a positive way. When the watt values reach the negative range (below the red line at 15-20° yaw), the cyclist benefits from the sail effect of the wheel with propulsion.
• Rotational Strength: Rotational strength accounts for up to 25% of the total strength compared to 75% of the translational strength. Since the spokes are the connection to the rim and the hub, they take on a significant importance that should not be underestimated in the fight against vento- the lower the height of the rim, the less the influence of the sail effect. Therefore, longer spokes in low rim profiles lead to higher rotational resistance.
• Steering moment: Lateral forces come into contact with the wheel and can affect drivability. Manoeuvrability must therefore be safe and predictable, regardless of external weather conditions, such as strong and changing transverse vento and vento the other way around. To achieve a controlled speed, the AERO+ rim is further refined in this regard with a lower steering moment. The rider benefits from more predictable, and therefore controlled, steering behavior, which results in longer periods in the aerodynamically optimal position and higher speeds.
• Rolling resistance: Wider tires tend to have a positive influence on rolling resistance. Due to their larger volume, they have a larger contact area and can be guided with lower air pressure without risking crushing them. Compared to the narrower contact area of narrow tires, the contact area of wider tires is "shorter". Thus, the tire deforms more easily and the rolling resistance decreases.

Ratchet Exp

• Easy maintenance: DT Swiss hubs are also known for notool technology. DT Swiss has also found a way to further improve this system and make maintenance even easier, with a small modification of the blanking caps.
• Freehub body conversion: Simplified thanks to easier disassembly.
• Less weight: Not only is reliability improved. The fusion of ratchet and threaded ring reduces the number of individual parts of the system, which offers an important advantage.
• Less wear: A single cylindrical spring ensures faster and more complete engagement and thus increases reliability
• Superior reliability: The full engagement of the ratchets creates a large contact surface and therefore a low surface pressure leading to superior reliability.
• Longer bearing life: Integration of the bearing into the threaded ring maximizes the bearing distance. The increased distance further supports the axle, which results in less axle deflection and thus protects the bearings and increases their service life.

Sinc Ceramic
SINC ceramic ball bearings were developed by DT Swiss. They are based on spheres made of silicon nitride (Si3N4), an extremely tough ceramic material that is resistant to wear and corrosion. The bearing rings are made of specially developed steel alloy, adapted to the properties of the specific ceramic material used and precisely ground. This combination reduces rolling resistance to an absolute minimum and ensures a longer service life than conventional ball bearings.
But it is not only the bearing itself that is conceived as a system. Only by using tolerances within a few thousandths of a millimeter and precisely adjusting the seat tolerances of DT Swiss hub bearings do Sinc ceramic bearings offer their full potential and offer the decisive advantage over competing products.
