It is the best tool to help you reach your maximum

Chosen by top professionals, the integrated power meter and the combination of lighter, stiffer, and more precise gears have just become lighter thanks to the new carbon crank arm structure. The SRAM power meter is accurate to +/-1.5% and is not affected by temperature changes, while the consistent 13-tooth spacing on the rings ensures fast and reliable shifting. Not only unbeatable in performance, the integrated rings are also incredibly durable. Additionally, SRAM offers more crank arm lengths than ever to ensure this crank fits you.
