Stronglight 2x10-speed chainring

Stronglight chainrings are CNC-machined from high-quality 7075-T6 aluminium. These chainrings are a high-quality and cost-effective replacement for original SRAM and Shimano chainrings.

The bolt circle is 64 mm or 104 mm, for Shimano and SRAM 9/10/11-speed drivetrains. The 104 mm bolt circle is the standard MTB bolt circle. The 64 mm bolt circle is currently the most common bolt circle for small chainrings on 9- and 10-speed MTB cranksets. The distance between the chainring bolts is 64 mm, measured diagonally from centre to centre.
