Stronglight ct² chainring

Stronglight chainrings are CNC-machined from high-quality 7075 aluminium and treated with ceramic Teflon for a long service life. Equipped with shifting aids, these chainrings are an equivalent and cost-effective replacement for the original Shimano and SRAM 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.

Thanks to the ceramic Teflon coating, these chainrings are particularly durable and long-lasting. The PTFE coating ensures quiet, low-friction running, whilst the Chain Shifting Assistance System ensures fast gear changes.

MTB bolt pattern 4-arm 140/64 mm

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