Our lightest, stiffest, and most precise combination of chainring and integrated power meter, appreciated by our professionals, is made even lighter with the new design of our carbon cranks. The SRAM power sensor offers an accuracy of +/- 1.5% and is not affected by temperature fluctuations. The constant distance of 13 teeth between the small and large chainring ensures quick and reliable gear changes. Our integrated chainrings prove to be incredibly durable. Additionally, we offer a wider range of crank lengths than ever before to ensure you find the crank that fits you.
