Sram Red E1 Chainring Powermeter 52T 12V DM - Black/Silver

This is the ultimate in integrated power measurement.
The RED AXS power meter kit adds Quarq technology to our RED chainrings for the lightest, stiffest and most accurate power meter available.
A 13-tooth difference on all chainrings ensures precise shifts for any configuration, as well as a less dramatic change in cadence during forward shifts.
Combined with our most durable chainrings ever, it's an unbeatable combination.

- The power meter is fully integrated into the chainring
- Measure the power on both crank arms.
- Very accurate with an error of only 1.5%
