Lightweight Obermayer EVO Carbon tubeless Disc front wheel

Lightweight Obermayer EVO - Incredibly light, incredibly stiff. Getting to the top requires more than just power.

The last curves of the mountain stage lie before you. While your competition has already spent its energy, you still have reserves. Thanks to a unique stiffness to weight ratio, each of your steps is transformed into direct propulsion without any loss of energy. The perfectly calibrated structure not only guarantees breathtaking performance, but also incredibly low weight. If you are looking for improved smoothness, increased stiffness, reliable brake safety and maximum acceleration, OBERMAYER EVO is your first choice.

When it came to the OBERMAYER EVO, Lightweight’s engineers didn’t leave anything to chance. That’s why they used LCC-Carbon, which has already been successfully tested and used in aerospace. Thanks to the Active Foam Core, they were once again able to save on weight and at the same time increase stiffness. Weighing in at only 1.230 grams, it is one of the lightest full carbon disc wheel sets available at the moment. The proven Rim-to-Rim design, combined with the Lightweight Performance Shape, ensures breathtaking acceleration. The full carbon spokes are directly connected to the wheel and, thanks to especially optimized CFRP fibers, make for unparalleled braking precision. The innovative Pentagon SL Hub is 60 grams lighter and improves heat dissipation during braking, subsequently increasing safety on long descents. The maximum allowed system weight of OBERMAYER EVO is 100 kilograms.

Less energy consumption during ascents and increased braking performance during descents – that is OBERMAYER EVO.

Every Lightweight wheelset is carefully handcrafted in Germany. As a result, slight deviations in colour and surface structure may occur. This is a characteristic quality feature of the high-quality manufacturing process. Lightweight stands for premium quality "Made in Germany".

Technologies

Lightweight Performance Shape
The components of Lightweight wheels are a perfect geometrical match. The rim with Active Foam Core, the Pentagon Hub design and Rim-to-Rim spokes are perfectly connected and allow the ultra-light and stiff construction of the Lightweight wheels. The monocoque construction with LCC carbon of Lightweight wheels is very elaborate and provides best stiffness-to-weight ratios (STW). In cross-section, rim and the directly connected spokes form an X which results in significantly less twisting at the wheel and even more of your power is transferred directly to the road.

Rim-to-Rim Design
Unlike the classic wheel design, Lightweight's carbon spokes run continuously from one side of the rim over 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 conventional spokes. Spokes can absorb tensile forces of up to 1,800 kilograms and are about 3 times stiffer than a steel spoke. The form-fit and material-fit (firmly laminated) connection of the carbon spokes to the hub and rim eliminates any deformation and ensures breathtaking propulsion. Furthermore, the type of connection leads to an enormously long life of the entire wheel, since the material barely fatigues.

Active Foam Core
On the Inside of the rim is high-performance foam core, called Active Foam Core. Through a patented process, Lightweight can build wheels not only lighter, but also gain significantly more stiffness due to less deformations. Compared to conventional designs without cores, the Active Foam Core has a vibration damping effect and consequently ensures a smooth ride.

LCC-Carbon
Not all carbon is the same. For Lightweight wheels they use only specially selected material, so-called Lightweight Custom Composite Carbon - LCC carbon. A special combination of very thin prepregs with high-strength and high-stiffness fiber types enables them to reduce wall thickness and sets new standards in both stiffness and weight without compromising on durability and safety.

Pentagon Hub
The Lightweight engineers have developed a unique design for maximum power transmission. The Pentagon Hub design is the technological heart of each disc-braked Lightweight wheel. It comes as a standard and SL version and is used in various Lightweight wheels. In the SL version (Super Light), the total weight has again been reduced by 70 grams (in the set) and the aerodynamics improved. The high heat that acts from the brake disc on the hub is reliably dissipated. The additional form closure by the hub housing in the form of a polygon (pentagon) ensures an extremely safe power flow from the tire to the brake disc. This increases safety, particularly on longer descents.
