Stronglight Chainring Type 130 ct² 5-arm, 130mm bolt circle, small chainring configuration, 38 teeth, colour: black, for Shimano and Sram 10-11-speed
Stronglight chainrings are CNC-machined from high-quality 7075-T6 aluminium. These chainrings are a high-quality replacement for the original SRAM and Shimano chainrings. The chainrings intended for use as a small chainring do not require and do not have shift guides.
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.
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.
