Magene Qed 110 Chainring Set

Aircraft-grade 7075 aluminium alloy has excellent physical properties, offering abrasion resistance, resistance to deformation, high stiffness and ultralight weight. Made from 7075 aluminium alloy, the entire chainring weighs just 143g while maintaining excellent performance. Based on the stress contours derived from FEA engineering analysis, we reinforced the structural design in areas subject to concentrated loads, reducing deformation under heavy loads. We create a perfect balance between weight, stiffness and durability, meeting the needs of professional cyclists in training and racing. *The QED lightweight chainring has passed more than 100.000 fatigue tests and over 40.000 kilometres of endurance testing.

CNC stands for Computer Numerical Control and represents a precision manufacturing process with uniform, consistent standards. The use of CNC technology ensures that all components work together flawlessly. With advanced CNC technology, machining and positioning techniques are effective and precise.

Following several product design iterations and studies of the performance and wear characteristics of various chainring tooth types, the QED lightweight chainring uses a new, internally developed third-generation tooth profile. As a result, drivetrain and shifting efficiency have been significantly improved.

We recalculated the parameters for the chainring tooth roots, grooves and profiles, making targeted adjustments to improve mechanical transition efficiency under heavy loads. This allows the chain to engage closely with the chainring and shift precisely and quickly from the small chainring to the large one.

At its fastest, the chain can shift onto the large chainring in 1/5 of a revolution. This ensures precise, smooth gear changes at different speeds and in different conditions.

The spacing between each tooth has been increased, and the strength between the teeth has been further improved, effectively extending the chainring's lifespan. Chain and chainring life has increased by approximately 3% compared with the previous version.

The QED lightweight chainring uses the widely adopted 110BCD 4-bolt specification, reducing weight and offering broader compatibility.

Magene also offers a spider-based power sensor solution alongside the chainring. A dedicated power meter can be used according to individual needs. The QED lightweight chainring is fully compatible with Magene's flagship QED P505 power meter and the entry-level PES P505 power meter.

The QED chainring is compatible with Shimano 11- and 12-speed groupsets.
