Know before you buy
While designed specifically for the Ultegra 6700 series, it is generally compatible with other Shimano 10-speed drivetrains. However, for optimal shifting performance and aesthetic matching, it is best paired with components within the 6700 series.
The B-Type designation refers to the specific tooth profiling and ramp-and-pin configuration engineered by Shimano for the 6700 series. This design is optimized to work with the matching inner chainring to ensure precise, reliable shifting under load.
No, this chainring is specifically engineered for 10-speed chains and drivetrains. Using it with an 11-speed system will result in poor shifting performance and increased wear due to the difference in chain width.
No, this product is the chainring only. You will need to reuse your existing chainring bolts or source a compatible set separately.
Check the model number printed on your existing chainring or consult your crankset's specifications to ensure it matches the Ultegra 6700 series. You should also verify your current bolt circle diameter (BCD) to ensure it aligns with the 6700 series standard.
