Stronglight XC-MTB chainring

Stronglight chainrings are made from high-quality steel. These chainrings are an equivalent and cost-effective replacement for the original Shimano chainrings.

Although specified by Stronglight for 9-speed drivetrains, these chainrings can also be used with 8- or 10-speed drivetrains. The spacing between the chainrings is determined by the crank arms.
