Upgrade your PRECISION to PRECISION PRO!

Ridden by the pros, PRECISION PRO dual-side power meters deliver all the benefits of our left-side model (exceptional accuracy, lightweight design, ANT+ and Bluetooth compatibility, 3D power meter technology), plus a specific breakdown of left and right wattage. Perfect for those who need specific power output from each crank side, or anyone who simply wants the best power meter on the market.

The PRECISION PRO Upgrade Factory Install is installed on your existing crank at our factory.

Note: Please see Factory Install crank compatibility list

How does it work?

We install PRECISION PRO on your existing crankset (at this time, your crankset must be a Shimano DURA-ACE FC-9000 series). You send us your crankset, and we install the power meter and send it back to you. Please note, new orders take approximately three to four weeks to be processed. We’ll be in touch via email to keep you posted on the status of your order.

For customers outside of Canada and the USA orders will be subject to applicable VAT and duties. 

If you have PRECISION Gen 1 you will need to send both your left and right cranks. Your Gen 1 PRECISION will be upgraded to a Gen 2 PRECISION as part of the Factory Install process. PRECISION Gen 1 

If you have PRECISION Gen 2 you will send only your right crank. PRECISION Gen 2

Don’t have a Shimano DURA-ACE FC-9000 series crankset? No problem.

Consider our PRECISION PRO Ride Ready, which comes with a Shimano DURA-ACE FC-9000 series crankset. 

Or check out our PRECISION LEFT-SIDE Factory Install or PRECISION LEFT-SIDE Ride Ready for more crank options for single-side power meters.
