Stronglight Type 130 ct² chainring

Stronglight chainrings are CNC-machined from high-quality 7075-T6 aluminium. These chainrings are an equivalent replacement for the original Sram and Shimano chainrings. The chainrings are designed for use as a small chainring and do not have shift guides

Stronglight ct²:

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

5-arm, 130 mm bolt circle

The chainrings with a 130 mm bolt circle are compatible with all 9- and 11-speed cranksets from SRAM and Shimano. The 130 mm bolt circle is not compatible with Campagnolo cranksets. You can easily determine the bolt circle by measuring the distance between two adjacent chainring bolts and multiplying this value by 1.7.
