With exceptional mechanical quality and excellent balance between weight and stiffness, the QED series can meet the demanding requirements of professional athletes during training or racing.
Excellent balance of stiffness, weight, and aerodynamics
The QED disc blades feature a hollow design, which can significantly reduce the overall weight. This weight reduction method does not affect the integrated stiffness of the disc, and you will see an excellent balance between stiffness and weight.
Precisely engineered application
The adoption of CNC technology ensures that all components work together seamlessly. Equipped with cutting-edge CNC technology, the machining and assembly are efficient and precise.
Improve transmission performance and gear shifting
After extensive research on the performance and wear characteristics of various tooth shapes of discs, the QED disc adopts a brand-new third-generation tooth shape. Transmission and gear shifting performance have been significantly improved. We have recalculated parameters related to root, groove, and tooth shape, ensuring accurate and smooth gear changes at different speeds under various conditions.
The width between the teeth is increased, and the strength between the teeth is further improved, effectively extending the lifespan.
Ultra-lightweight 7075 aircraft-grade aluminum
The 7075 aluminum alloy has excellent physical properties, offering resistance to friction, deformation, high stiffness, and extremely light weight. The larger disc is made from 7075 aluminum alloy, making the QED set weigh only 138 grams while maintaining excellent performance.
110BCD with 4 bolts, wide compatibility
The QED disc blades adopt the widely popular 4-bolt 110BCD standard on the market, which reduces weight and offers broader compatibility. They can be perfectly adapted to 12-speed series, aiming for top performance to meet the strict training and racing needs of riders. The lightweight split disc blades are fully compatible with Magene’s QED P505 cadence meter and PES P505 cadence meter.
