EXTRALITE Wheelset 28" Road | CyberDisc 340C with Carbon Spokes
The CyberDisc 340C from Extralite is a road wheelset in a class of its own! Designed for competition, the 888g lightweight wheels offer impressive acceleration and are made for the steepest ramps in the race profile. The medium-height aero rims are made of special high-performance fibers from Toray. The leading manufacturer of high-quality carbon fibers forms the basis for many exciting lightweights on the market. Very light Hi-Rigidity Fiber is used, which is characterized by exceptional stiffness and stability. The asymmetrical arrangement of the spoke holes achieves a more even spoke tension, which increases the reliability of the wheelset and minimizes maintenance. The generous inner and maximum outer width of the rims are optimized for tire widths of 25 to 32 millimetres and integrate the rubber in an aerodynamically favourable manner. The wheelset is ideal for tubeless use in order to take full advantage of the improved puncture protection and rolling resistance properties of modern tubeless tires.
CyberHub SPD 3+ Hubs
The ultra-light Extralite CyberHub SPD 3+ hubs are an Italian masterpiece. The one-piece hub body is precisely manufactured from high-strength 7075TX aluminum using state-of-the-art CNC technology. 7075TX is a variant of the 7075 aluminum alloy, which is mainly used in the aerospace industry due to its particular hardness and resistance. The alloy offers a perfect combination of low weight and high strength, making it ideal for critical applications where high structural integrity is required. At the center of the hub, double-sealed stainless steel bearings rotate on a 17 millimeter thick aluminum axle. The axial play can be precisely fine-tuned via a micro-tuner to prevent unwanted movements and vibrations. Thanks to the straightbull design, the spokes are bolted directly into the hub instead of being guided through traditional storage holes. This ensures a considerable reduction in weight, increases the load capacity of the wheels and gives them a modern appearance. A pawl freewheel provides propulsion. Two pawls engage in a titanium ring with 32 engagement points. This reduces the free travel and also reduces wear.
Carbon Spokes
Carbon spokes are the preferred choice wherever high stiffness and low weight are important. They improve the energy transfer and responsiveness of the wheels. In addition, carbon spokes absorb vibration more effectively than conventional metal spokes.
All Extralite wheels are handcrafted in Italy with high precision and creative passion and stand for outstanding performance, exceptional lightness and a quality of workmanship that is second to none.
