It’s the best tool to help you reach your best. The choice of our top professionals, our lightest, stiffest, and most accurate integrated power meter and chainring combo just got lighter with a new carbon crankarm construction. The SRAM power meter is accurate to +/-1.5% and isn’t affected by temperature changes, and the consistent 13-tooth gap on the rings ensures fast and reliable shifting. Not just unbeatable on performance, our integrated rings are also incredibly long-lasting. Plus we’re offering more crankarm lengths than ever before to ensure this crank works for you.
