Lightweight Obermayer EVO Schwarz ED Tubeless Disc Wheelset

To keep up with the best, you need materials that guarantee precision, performance and safety. Thanks to a unique stiffness-to-weight ratio, OBERMAYER EVO turns every pedal stroke into maximum propulsion without any loss of energy. OBERMAYER EVO is Lightweight's highest-performing disc brake wheel and is suitable for (mountain) roads, training and racing.

OBERMAYER EVO is a further development of the popular MEILENSTEIN OBERMAYER wheel and is available as a disc brake model. The tubeless version offers the best stiffness-to-weight ratio and maximum heat resistance. OBERMAYER EVO is particularly light and is one of the lightest, most exclusive and most powerful disc brake wheels in the world.

The engineers at Lightweigt have left nothing to chance. That is why they used LCC carbon, already tested and successfully used in the aerospace industry. Thanks to Active Foam Core, they have once again managed to reduce weight and increase stiffness. The proven Rim-to-Rim design, combined with Lightweight Performance Shape, ensures breathtaking acceleration. The full carbon spokes are directly connected to the wheel and, thanks to specially optimised CFRP fibres, ensure unparalleled braking precision. The innovative Pentagon SL hub is 60 grams lighter and improves heat dissipation during braking, increasing safety on long descents. The maximum permitted system weight for OBERMAYER EVO is 100 kg.

Lower energy consumption on climbs and greater braking performance on descents: this is OBERMAYER EVO.
Every Lightweight wheel is carefully handmade in Germany. As a result, slight variations in colour and surface texture may occur. These are a mark of the quality of the manufacturing process. Lightweight stands for premium quality "Made in Germany".

Technology

Lightweight performance shape
The components of Lightweight wheels are a perfect geometrical match. The rim with Active Foam Core, the Pentagon hub design and the Rim-to-Rim spokes are perfectly connected to each other, enabling the ultralight, stiff construction of Lightweight wheels. The monocoque construction of Lightweight wheels using LCC carbon is highly sophisticated and provides the best stiffness-to-weight ratios (STW). In cross-section, the rim and directly connected spokes form a X, resulting in less wheel twisting and greater power transfer directly to the road.

Rim-to-Rim design
Unlike conventional wheel designs, Lightweight's carbon spokes run continuously from one side of the rim through the hub to the other side of the rim. This so-called Rim-to-Rim design provides extremely high torsional and lateral stiffness that cannot be achieved with traditional spokes. The spokes can withstand tensile forces of up to 1.800 kg and are approximately 3 times stiffer than a steel spoke. The connection of the carbon spokes to the hub and rim, through both their shape and material bonding (firmly laminated), eliminates any deformation and ensures breathtaking propulsion. This type of connection also ensures exceptional durability for the entire wheel.

Active Foam Core
Inside the rim is a high-performance foam core called Active Foam Core. Thanks to a patented process, Lightweight can build wheels that are not only lighter but also significantly stiffer thanks to reduced deformation. Compared with traditional models without a core, Active Foam Core has a vibration-damping effect and consequently ensures a smooth ride.

LCC carbon
Not all carbon is the same. Only a specially selected material is used for Lightweight wheels, known as Lightweight Custom Composite Carbon - LCC carbon. A special combination of very thin prepregs with high-strength, high-stiffness fibre types allows wall thickness to be reduced and sets new standards in stiffness and weight without compromising durability and safety.

Pentagon Hub
Lightweight engineers have developed a unique design for maximum power transfer. The Pentagon hub design is the technological heart of every Lightweight disc brake wheel. It is available in standard and SL versions and is used in various Lightweight wheels. In the SL (Super Light) version, the total weight has been reduced by a further 70 grams (per set) and aerodynamics have been improved. The intense heat transferred from the brake disc to the hub is reliably dissipated. The additional mechanical interlock of the polygonal (pentagonal) hub housing ensures extremely secure power transfer from the tyre to the brake disc. This increases safety, especially on longer descents.
