Shimano Dura Ace R9100 Crankset with Wattmeter

Watt meters (or power meters as they are also called) have become more and more widespread in recent years and now Shimano has finally developed one for their best racing group - Dura Ace.

Measures watts on both legs.

The crankset comes without chainrings so you can decide your gearing yourself.

The pedal arm length is optional.

Both sides are included.
