Lightweight, the German wheel manufacturer known for pioneering carbon road wheels with bonded spokes in 1994, has introduced its latest innovation: the Meilenstein ART wheelset. This new offering continues Lightweight’s tradition of combining carbon rims and carbon spokes bonded directly to the hub, but with significant updates that align the wheelset with modern cycling demands. The Meilenstein ART represents Lightweight’s first new wheelset since the Fernweg Evo Pro and aims to balance lightweight performance, aerodynamics, and stiffness while accommodating wider tires and modern rim widths.
Key Innovations
-
Alpha Rib Technology (ART)
The standout feature of the Meilenstein ART is its Alpha Rib Technology (ART), which introduces an internal rib structure within the rim. This patented design replaces traditional foam-core or hollow builds with a network of carbon ribs, improving structural integrity and reducing weight. Lightweight claims this innovation results in a 20% improvement in aerodynamic efficiency compared to the previous Meilenstein EVO wheelset. The ART also enhances lateral stiffness, making the wheels more responsive and durable. -
Rim Design and Dimensions
The Meilenstein ART features a 45 mm rim depth and a 22.9 mm internal width, optimized for modern tires sized 28 mm and above. The Drag Reduction Shape (DRS) of the rim was developed using computational fluid dynamics (CFD) to optimize aerodynamics and stability across various riding conditions. -
Rim-to-Rim (R2R) Spokes
Lightweight’s signature Rim-to-Rim (R2R) design continues here, with full-carbon spokes bonded directly to both the rim and hub. This eliminates mechanical interfaces like nipples or threads, reducing weight and potential failure points while creating a direct transfer of power from the rider to the road. -
Penta-Fly Hub System
At the center of the wheelset is the Penta-Fly hub architecture, which features oversized flanges for lateral stiffness and a minimized central hub diameter to reduce drag. The wheelset is available in two versions:- Standard: Equipped with steel bearings.
- Schwarz Edition: Upgraded with CeramicSpeed bearings for smoother performance.
-
Aero-Mass Index
Lightweight has introduced a new metric called the Aero-Mass Index, which combines drag and weight into a single performance score. The index measures the watts required to maintain 45 km/h (28 mph) multiplied by the wheelset’s weight. A lower score indicates a better balance between speed and overall performance. According to Lightweight, the Meilenstein ART achieves the lowest Aero-Mass Index in its class, offering best-in-class stiffness and aerodynamic efficiency. -
Aesthetic and Manufacturing Precision
The wheelset marks a visual departure from Lightweight’s traditional woven carbon look. Instead, it features a raw UD carbon finish, reflecting the precision of its manufacturing process. Each wheel is constructed using over 500 meters of carbon fiber and 70 individual plies.

Availability and Options
The Meilenstein ART wheelset is initially available in a 45 mm rim depth. It offers three freehub options, all based on DT Swiss 180 EXP hub internals. Riders can choose between the Lightweight Silver version with steel bearings or the Lightweight Black Edition with CeramicSpeed bearings.
Conclusion
The Meilenstein ART represents a significant step forward for Lightweight, combining cutting-edge technology with a modern aesthetic. Its innovative Alpha Rib Technology, Rim-to-Rim spokes, and Penta-Fly hub system deliver a lightweight, stiff, and aerodynamically efficient wheelset designed for high-performance cycling. While the €6,550+ price tag places it firmly in the premium category, the Meilenstein ART is positioned as a top-tier option for riders seeking the ultimate in speed, responsiveness, and durability.
