QED Split Chainring

Magene QED Split Chainring

Experience a transformative shift in your drivetrain performance with the QED Split Chainrings, where elite-level stiffness meets an impossibly light 143g profile. Precision-engineered from 7075 aircraft-grade aluminum using advanced FEA stress contour analysis, these chainrings are strategically reinforced in high-load zones to eliminate power-robbing flex. Whether you are throwing down a massive watt-surge in a final sprint or grinding through a steep alpine ascent, the CNC-machined construction ensures your energy is transferred directly to the road with unwavering reliability and abrasion resistance that stands up to the rigors of racing.

Beyond the weight savings, the QED’s third-generation tooth profile redefines what "fast shifting" actually feels like. Designed to execute shifts from the small to the big ring in as little as one-fifth of a crank revolution, this system maintains crisp, buttery-smooth transitions even under the heavy torque of a climb. Compatible with 110 BCD 4-bolt systems and optimized for Shimano 11 and 12-speed groupsets, it is the ultimate upgrade for the weight-conscious cyclist who refuses to sacrifice shifting speed or mechanical efficiency.
