About the DT Swiss ARC 1100 38 CS

The DT Swiss ARC 1100 38 CS 2026 wheelset was developed to offer the lightest solution in the Aero range to date, now featuring carbon spokes. Designed for demanding climbs where every gram counts and oxygen is scarce, it positions itself as a perfect partner for ascending mountain roads with fluidity and efficiency.

Carbon fiber spokes and optimized construction

Spokes are one of the cornerstones of DT Swiss expertise. The introduction of carbon spokes marks a significant milestone in the brand's evolution. Their design offers a considerable weight reduction while simultaneously enhancing the overall robustness of the system. Each wheel is hand-assembled by DT Swiss 's expert wheel builders, guaranteeing precision and reliability that meet the most demanding standards.

38mm PURE Carbon Rim

The 38mm deep rim is manufactured in-house using PURE Carbon technology. This construction significantly reduces weight while improving climbing performance. The optimized aerodynamic profile helps maintain speed, especially on moderate climbs, while providing a stable and efficient ride.

WTS wheel-tire system

The ARC 1100 38 CS 2026 wheels come with a WTS setup designed to maximize climbing speed and descending stability. The front wheel is fitted with a 26mm AERO 111 tire, while the rear wheel is equipped with a 28mm Continental GP 5000 STR. This combination ensures reliable grip, high efficiency, and great confidence on mountainous terrain.

Lightweight and high-performance in the mountains

Weighing approximately 1200g per pair, these wheels offer a decisive advantage on the steepest climbs. They are designed to accompany cyclists on demanding routes, where speed, control, and comfort come together to reach new heights.

Alpine inspirations and collaborative project

The iconic landscapes around Andermatt and the legendary climbs of the Furka Pass inspired the design of the ARC 1100 38 CS 2026. They were notably presented on the new BMC mountain bikes during climbs where every pedal stroke highlights the efficiency of the system.

This achievement is part of a collaborative project celebrating the spirit of mountaineering cycling. A unique bicycle, designed as a tribute to great climbs, was unveiled at an exclusive event at Rouleur Live in London. Cyclists, media, and enthusiasts were able to discover the union of technological innovation and alpine tradition, conceived to offer a climbing experience that combines lightness and performance.
