DT Swiss ARC 1400 Dicut 55 Carbon Disc Tubeless Ready front wheel

Take the lead of your next ride with our fast and controllable wheels

The lead over your friends and rivals won’t just be given out to you. You will have to train hard to reach your goal. Helping you on your quest is the third generation of the benchmark ARC 1400 DICUT now ideally suiting wider tires. Available in three new rim heights, 55, 65 and 85 mm, with a unique v-shape that allows for a wider inner width without compromising aerodynamics. The ARC 1400 DICUT 38, with its 38 mm high rim remains the ideal climbing wheelset for blasting through the iconic climbs on your bucket list. Combined with top-of-the-line 240 DICUT hub with Ratchet EXP system and DT aerocomp II spokes, will help you take the lead in your next ride.

ARC 1400 DICUT 55
Conquer the title of climber: these wheels offer good aerodynamic performance, are very manoeuvrable and their low weight will be your best ally when climbing.

Wider inner rim width
The 22 mm wide inner rim width, ideally supports wide tires (28 to 30 mm) for enhanced comfort.

V-shaped rim
The newly developed rim shape provides a lower frontal area for less base drag.

Aero WTS
Available as an aero-optimized wheel tire system (WTS) mounted with the new AERO 111 tire in the front.

Aero spokes
The latest generation of our aero spokes, DT aerocomp II providing low rotational and translational drag.

Hub
The 240 DICUT hubs provides the reliability of the Ratchet EXP system.

Reborn lighter, rise faster
The climbing wheelset with a 38 mm rim height and a narrower 20 mm inner width ensures a low weight to conquer the steepest climb.

Technologies

WTS Technology
Optimising wheel and tyre 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 tyre as a complete system: the Wheel Tire System (WTS). With AERO 111, we developed the ideal front tyre tailored to the wheel, taking aerodynamic optimisation to the next level. The development of the complete wheel-tyre system (WTS) is part of our AERO+ concept, a perfect synthesis of strength, handling and efficiency. We have applied this technology to our Aero and Endurance categories, taking their aerodynamic advantages to the next level with a tailor-made tyre that fits perfectly within the respective inner rim widths.

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

Ratechet EXP technology
Hubs are known for their no-tool technology. We have found a way to perfect this system and further simplify
