ARC 1100 Dicut® DB 50 Carbon Aero Road Rear Wheel 28"/700C SHIMANO HG / SRAM XDR

With a 50 mm deep AERO+ profile rim, fine-toothed Ratchet EXP freewheel and SINC Ceramic ball bearings, the ARC 1100 Dicut® DB 50 Carbon is the ultimate ”rouleur” rear wheel in DT Swiss’ aero line-up with perfect all-round qualities!

With high stiffness and low weight, the optimised generation of the ARC 1100 Dicut® system wheel lets you roll along in the peloton, master curvy climbs with élan and set your final attack at the right time. The agile wheel is not only characterised by low air resistance, it can also be controlled excellently in strong crosswinds to fully develop its potential on hilly or flat tracks with tight corners. Besides, the carbon wheel is also the perfect choice for all smaller and lighter riders who don’t want to do without aero wheels. High stiffness values and the wheel’s low weight impress pros and ambitious amateur cyclists alike – in fact, all those who like to ride fast.

The leading component technology by DT Swiss and SWISS SIDE’s know-how in aerodynamics give the carbon wheel unparalleled control and aero stability. The AERO+ carbon rim that was developed based on sophisticated, computer aided simulations and numerous wind tunnel tests is just one part of the entire aerodynamic wheel system optimised for use in combination with powerful disc brakes.
The ARC 1400 carbon wheel not only impresses with its medium-high AERO+ profile rim. It is extremely resistant against wind shear and crosswinds and rotates at top speed around the legendary 180 hub with aerodynamic DT Swiss bladed spokes. With its outstanding SINC Ceramic bearing, it ensures maximum efficiency and smooth running with particularly high durability. The weight-reduced Ratchet EXP freewheel system for impulsive acceleration tops off the first-class construction of the ARC 1100 Dicut®DB 50 carbon wheel.

Excellent tubeless compatibility provides less weight, improved puncture resistance, lower rolling resistance and more comfort when equipped with tubeless tyres.

Technologies:

AERO+:
The symbiosis of air resistance, handling and efficiency. – The optimisation of the wheel aerodynamics by DT Swiss in cooperation with SWISS SIDE reduces rotational and air resistance for low-friction acceleration and controlled steering behaviour in crosswinds. In combination with a larger inner rim dimension for wider tyres, rolling resistance is also reduced. Traction and comfort are enhanced by the wide contact patch.

RATCHET EXP SYSTEM:
Thanks to the integration of star ratchet and thread ring, this is currently the lightest ratchet freewheel system from DT Swiss. The start ratchets for the Ratchet EXP system have 36 or 54 teeth for a particularly small engagement angle. The system stands out for high reliability thanks to the simultaneous meshing of the teeth, which leads to significantly lower point loads. The no-tool concept allows easy maintenance and tool-free conversion to common axle and freehub body standards.

SINC CERAMIC:
The SINC Ceramic ball bearing, developed as a system by DT Swiss, ensures optimal functioning in all conditions with minimal friction. Particularly resistant ceramic balls made of silicon nitride (Si3N4) in combination with precision-ground steel bearing rings reduce rolling resistance. The sealed hybrid bearing is wear and corrosion resistant and promises particularly high durability. Each DT Swiss SINC bearing is individually checked, precisely adjusted to the tolerances of the hub bearing seats and tested.

TUBELESS:
All DT Swiss wheels are tubeless ready. The profiles of the DT Swiss rims are specially designed for tubeless use. The rim profile makes it easier to fit the right tyre and ensures a perfect fit. The tubeless system of the rim consists of DT Swiss tubeless ready tape for sealing and a DT Swiss tubeless valve in a length that complies with the rim. When using tubeless ready tyres, a compatible sealant must be used. However, it is also possible to use a conventional combination of tyre and inner tube.

BEARINGS:
Having learned from years of experience, DT Swiss only uses durable cartridge bearings without bearing play adjustment. DT Swiss hubs are designed to have the optimum axial and radial bearing play when they are properly installed. The correct preload of the bearings to compensate for the clamping force of the wheel mounting system is the basis for a play-free hub with minimum friction.
