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

How to calculate gear inches for an oval chainrings
Exactly same way as for round chainring. You just need to use the nominal size in the calculation of an oval ring you have. That is, if you buy 32T oval you use for calculation 32T size. Reason for this is 32T oval chainring has same circumference as the 32T round. We optimize the shape but not circumference - it stays constant. Distance between each teeth always has to remain at 12.7mm to engage the chain properly. You can use any online calculator to get gear inches for an oval chainring.
Which size of an oval should I choose
We always recommend swapping like for like, so if you have a 32T round ring at the moment, you should consider getting a 32T oval. The same applies to our shiftable road ovals, we recommend that you purchase ovals with the same teeth count as your round rings.
