Overview

About this product

A high-precision, ultra-light chainring engineered for riders who demand maximum stiffness, smooth shifting, and race-ready durability. Constructed from 7075 ultra-light aircraft aluminium, the QED Lightweight Split Chainring offers outstanding stiffness, abrasion resistance, and deformation resistance while weighing only 143g. This makes it an ideal upgrade for riders seeking improved performance without compromising durability.

Using FEA-based stress contour analysis, Magene reinforces high-load areas to minimise flex under power, ensuring consistent performance during sprints, climbs, and long-distance efforts. Precision CNC machining guarantees uniformity, accurate tooth shaping, and perfect alignment for reliable drivetrain engagement. Magene's third-generation tooth profile enhances chain retention, shifting speed, and overall transmission efficiency.

Redesigned tooth roots, grooves, and shapes allow the chain to move from the small ring to the big ring in as little as one-fifth of a crank revolution, even under heavy load. Compatible with 110 BCD 4-bolt systems, the QED chainring integrates seamlessly with Magene's P505 power meter and supports 11 and 12-speed Shimano groupsets (excluding Shimano cranksets with unique shapes).

A high-precision, ultra-light chainring engineered for riders who demand maximum stiffness, smooth shifting, and race-ready durability.
