Power Measurement:

This SRM power meter measures power at the spider and is therefore able to measure power from both legs.

Key Features:

Advice From Our Staff:

There is no getting around it, this is a pricy power meter. SRM power meters are expensive, as are Campy components, and when you combine the two, you have a $2,000+ power meter. However, when it comes to a Campy power meter crankset, it’s as good as you can get. It’s highly accurate, stiff, lightweight, has a rechargeable battery, looks amazing and comes with a solid 2-year warranty. In addition, it can be used with either 11- or 12-speed chainrings.



Crank Arm:

The Campy crank arms are available in the following sizes:

  • 170 mm | 172.5 mm | 175 mm


If you would like to purchase the power meter with chainrings, available chainring options are:

  • Campy 12-Speed Chainrings: 50/34 | 52/36 | 53/39
  • You may also order the power meter without chainrings and use your own 11- or 12-speed Campy chainrings

PC8 Bundle:

While not listed as an option above, you can bundle your SRM with a SRM PC8 Bike Computer. When you do, you get $249 off the standard price of the PC8. Please contact us if you would like this option.


The SRM Campagnolo Power Meter comes ready for use with 12-speed drivetrains. You can also install 11-speed Campy chainrings on the power meter.
