Shimano Ultegra Chainring

No, this chainring is specifically engineered for 10-speed drivetrains. Using it with an 11-speed system will likely result in poor shifting performance and potential chain drop due to the different chain widths.

You need to measure the Bolt Circle Diameter (BCD) of your existing crankset. The BCD is the diameter of the circle formed by the center of the chainring bolts; if your crankset is 130mm, this ring will bolt on perfectly.

While it is optimized for Shimano 10-speed systems, it will generally work with most standard 10-speed chains from other manufacturers. However, for the crispest shifting performance, we recommend sticking with a Shimano-compatible chain.

No, this is specifically designed as an inner chainring. The ramp and pin profiles, as well as the tooth shaping, are optimized for the inner position and will not provide the necessary shifting performance if installed as an outer ring.

No, this product includes only the chainring itself. You will need to reuse your existing chainring bolts or purchase a new set separately if your current ones are damaged or seized.
