Magene QED 110/4 BCD 11/12 Speed Chainring Set

The QED chainring set is Magene's own lightweight, split-design chainring line, machined from 7075 aircraft-grade aluminium alloy - a step up from the standard 6061 alloy used on many aftermarket rings.

It's built around the 110mm, 4-bolt asymmetric BCD standard, matching Shimano's own bolt pattern for 11 and 12-speed shifting compatibility - useful if you're running a non-Shimano crankset or a power-meter spider that shares the same bolt circle, since the rings themselves are not designed as a direct swap onto genuine Shimano crank arms. Magene's own third-generation tooth profile is built with optimised tooth-root spacing, claimed to help the chain shift onto the big ring within about a fifth of a crank revolution.

In practice, this is the chainring set for a rider upgrading or replacing rings on a 110/4-BCD crankset or power meter, rather than someone looking to retrofit a genuine Shimano crank.

Why You'll Like It

Genuinely lightweight: the 50/34T set weighs around 143g for both rings together, thanks to the split design and 7075 alloy construction.

Shimano-compatible shifting: built to the same 110/4 asymmetric BCD standard, so shift quality matches what you'd expect from a Shimano 11/12-speed drivetrain.

A refined tooth profile: Magene's own tooth-shape design is built to shift onto the big ring quickly and cleanly.

CNC-machined for precision: 7075 alloy, CNC-machined, built to hold a consistent, precise shape ring after ring.

Who Is It For?

Riders running a 110/4 asymmetric-BCD crankset or power-meter spider (including Magene's own QED power meter) who want to upgrade or replace their chainrings without buying an entirely new crank.

It's not the right choice if you're looking to retrofit rings directly onto a genuine Shimano crank arm - check your crankset's compatibility with the 110/4 asymmetric standard before ordering.

Good to Know

• Confirm your crankset or power-meter spider uses the 110mm, 4-bolt asymmetric BCD standard before fitting.
• Torque chainring bolts evenly and to your crank manufacturer's spec for consistent shifting.
• Keep the rings clean and lightly lubricated at the chain contact points for the smoothest shifting performance.
