Compatible with SHIMANO GRX 110BCD AERO Narrow Wide Chainring

The G110BCD chainring is CNC-machined from a single piece of aluminum, featuring precision thinning and chamfering to reduce weight while maintaining strength. With extended tooth profiles, it securely holds the chain in place—even under intense vibration—effectively preventing chain drops.

We patiently polished the tooth shape

the position of the upper chain pin

and the orientation of the lower chain slot to eliminate chain noise

reduce wear, and provide smooth operation for the entire riding system

The sprocket has been proofread and adjusted many times

and has good fit. While reducing the weight as much as possible

it still maintains sufficient rigidity to meet the needs of daily riding and competition.

To reduce weight,

we applied extensive thinning throughout the chainring

This design not only enhances its appearance and lightness

but also maintains the rigidity needed for reliable performance

The GRX series has small holes

Ordinary X110 cranks (5800/6800/9000, etc.)

              and power meter claws cannot be used

7075 aluminum is known to be challenging for anodizing

To overcome this we conducted multiple rounds of prototyping

to ensure the chainring is well-protected against mechanical impact—while also delivering an exceptional surface finish and tactile feel on every piece
