Fully integrated wattmeter for maximum rigidity and precision.

This red AXS wattmeter is integrated on the chainring, making for a very rigid system.

The chainring is an aero type where there is only one chainring. This is chosen to reduce complexity.

The wattmeter is accurate to within 1.5% plus/minus and the reading does not change despite changes in temperature and the like.

The chainring is of the X-Sync narrow-wide type, which ensures that the chain is kept well in place.

This wattmeter and chainring mounts with direct mount on newer 8-bolt systems.

Suitable for RED and Force eTap AXS cranksets.
