SRAM RED chainrings D1 – Chainrings with power meter

It is the ultimate integrated power measurement system. The RED AXS power measurement kit complements SRAM's one-piece chainrings with Quarq technology to create what is arguably the lightest, stiffest, and most accurate power package on the market. A 13-tooth spacing on all chainring pairs ensures precise shifting in any setup and less dramatic cadence changes when shifting. Combined with SRAM's most durable chainrings, this is an unbeatable combination. The power meter has an accuracy of +/-1.5% and is not affected by temperature fluctuations.

Features:
Crisp and precise front shifting
One-piece construction for faster, smoother, and safer shifting
The power meter is fully integrated into the chainring
Power Balance measures separate values for the left and right legs
