The journey of training and advancement unfolds throughout a professional rider's career. With its exceptional mechanical precision and an artful equilibrium of weight and rigidity, the QED series thrives under the demanding requirements of both training and competition. It consistently empowers riders to experience the innate prowess of mechanical excellence.
The QED split chainring boasts a carefully engineered design that significantly reduces overall weight without compromising the integrated stiffness of the chainring.
Harnessing the precision of CNC technology ensures flawless synergy among components. Employing cutting-edge CNC techniques, the manufacturing and positioning processes to make these chainrings are executed with utmost precision.
Through extensive research into performance and wear patterns of various tooth-shaped chainrings, the QED split chainring embraces a groundbreaking 3rd generation tooth design. This innovation results in a substantial enhancement in transmission and shifting efficiency. The root, groove, and tooth shape parameters have been carefully recalculated, guaranteeing seamless shifting across a range of speeds and conditions. The increased tooth spacing and reinforced tooth strength dramatically extend the lifespan of the QED chainrings.
Crafted from 7075 aircraft-grade aluminum alloy, renowned for its exceptional physical properties, this chainring offers remarkable resistance to wear, and deformation with high stiffness, and are incredibly lightweight. The chainrings, constructed from 7075 aluminum alloy, ensure the QED split chainring weighs a mere 138g while maintaining outstanding performance.
The QED split chainring adopts the widely acclaimed 110BCD 4-bolt specification, reducing weight and expanding compatibility. It seamlessly integrates with 12-speed groupsets, catering to the exacting demands of riders in pursuit of peak performance during training and competition.
* QED lightweight split chainring is compatible with the Magene QED P505 power meter and PES P505 Base power meter.
