Overview

Exquisite Balance of Stiffness, Weight and Aerodynamic

The QED split chainring features hollow design, which can greatly reduce the overall weight. In this method of reducing weight, it won‘t affect integrated stiffness of the chainring, and you will see the exquisite balance between stiffness and weight.

Precise Synergy of All Parts

Adopting CNC technology ensures that all components work together to function flawlessly. Featuring the cutting-edge CNC technology, the machining and positioning technique is effective and accurate.

Improve Transmission and Shifting Efficiency

After multiple research on the performance and wear characteristics of various tooth-shaped chainrings, the QED split chainring adopts a brand new self-developed 3rd generation tooth shape. The transmission and shifting efficiency have been significantly improved. We re-calculate parameters related to the root, groove, and shape of teeth on the chainring, ensuring accurate and smooth shifting at a different speeds in different conditions. The width between the teeth is increased, and the strength between the teeth is further improved, which effectively prolongs the service life.

Ultralight 7075 Aircraft-Grade Aluminum

7075 aircraft-grade aluminum alloy has excellent physical properties, offering abrasion resistance, deformation resistance, high stiffness and ultralight weight. The larger chainring is made of 7075 aluminum alloy, which makes the QED split chainring only weighs 138g while maintaining such excellent performance.
