The SRAM RED AXS FC-RED-P-E1 Power Meter Crankset is the flagship choice, the lightest, stiffest, and most accurate integrated power meter and chainring combination SRAM has ever produced. A new carbon crankarm construction shaves 29g over the previous generation, bringing the total weight down to an exceptional 580g. Accuracy is rated at +/-1.5% and is unaffected by temperature fluctuations during a ride, so your data stays reliable no matter the conditions. The consistent 13-tooth gap between the chainrings delivers fast, reliable front shifts, and the integrated rings are built to last. With more crank arm lengths available than ever before, there's a fit for every rider.
