Shimano SLX M660 Chainring

Yes, this chainring is specifically engineered for 9-speed systems. As long as your crankset utilizes a 104mm BCD (Bolt Circle Diameter), it will integrate seamlessly with your existing setup.

You can verify this by measuring the distance between the center of one chainring bolt hole to the center of the adjacent bolt hole. For a 104mm BCD, this distance will measure approximately 73.6mm.

You can replace your existing chainring with this 32T option, but keep in mind that changing the tooth count will alter your gear ratios. You may need to adjust your chain length or front derailleur height to accommodate the difference.

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 hardware is worn or damaged.

While it is designed for 9-speed systems, it may physically fit, but it is not optimized for the narrower chain widths used in 10-speed or 11-speed drivetrains. For the best shifting performance and longevity, we recommend sticking to a 9-speed chain.
