Shimano 105 R7000 Chainring

This chainring is specifically designed for the Shimano 105 R7000 crankset, which uses a 110mm asymmetric bolt circle diameter (BCD). It is not compatible with older 5-arm cranksets or non-Shimano asymmetric mounting standards.

No, this chainring is engineered specifically for 11-speed road drivetrains. Using it with other speed systems will likely result in poor shifting performance and potential drivetrain damage.

The asymmetric design aligns the chainring's structure with the areas where you apply the most force during your pedal stroke. This helps optimize power transfer and ensures the chain moves smoothly between rings for more consistent shifting.

While you can replace just one, it is often best practice to replace both if your drivetrain has significant wear. Replacing them together ensures the teeth profiles match perfectly, which helps maintain smooth shifting and extends the life of your chain.

While it is optimized for Shimano 11-speed chains, it will generally work with most high-quality 11-speed chains from other manufacturers. However, for the crispest shifting performance, sticking with a Shimano HG-X11 chain is recommended.
