Through our patented 3D strain gauge technology, you have the assurance knowing that the data you depend on will help lead you to your own Yellow Jersey.

The PRECISION PRO Ride Ready comes pre-installed on a new Shimano crankset.
How Does It Work?
A set of ride ready PRECISION PRO pods are already preinstalled on a brand-new Shimano crankset at our factory. The moment you order, our fulfillment team will get it on its way to you, and you should be able to ride with dual-sided power as soon as it arrives.
Important: You need to use the frame clearance pages below to ensure there is space between your crank and frame for the PRECISION PRO pods.
What do I get?
Once your ride-ready PRECISION PRO powermeter arrives, it just needs to be installed on your bike using the standard Shimano crankset installation process. Connect a headunit or computer, and you can start riding with power!
