Shimano 105 5800 Chainring

While designed for the 5800 series, this chainring is generally compatible with other Shimano 11-speed road cranksets that utilize the same 110mm asymmetric bolt pattern. However, for the best shifting performance and aesthetic match, it is recommended to stick with the 5800 series or compatible 105-level components.

You will need a standard set of hex keys to remove your crankset and chainring bolts. If you are replacing the chainring while the crank is still on the bike, ensure you have a chainring bolt tool to hold the back of the nut in place while you unscrew the bolt.

No, this chainring is specifically engineered for 11-speed chains and drivetrain spacing. Using it with a 10-speed chain may result in poor shifting performance, increased noise, and premature wear on the chainring teeth.

You should inspect your chainring if you notice your chain skipping under load or if the teeth appear 'hooked' or shark-finned rather than flat-topped. If you are replacing your chain and cassette due to wear, it is often a good time to check the chainring for similar signs of fatigue.

The asymmetric 110mm bolt pattern places the mounting bolts in positions that better support the chainring where the most pedaling force is applied. This design increases stiffness and reduces flex, ensuring that your power transfer is more efficient during hard efforts.
