Note: Due to limited quantities available, clearance and reCYCLED cranks are eligible for a 60-day no-questions-asked return policy, but we cannot guarantee replacement.

Previously ridden cranks are refurbished and have passed all appropriate quality-control checks for functionality, but may have some cosmetic blemishes.

Your Ride Ready PRECISION includes a brand new 4iiii PRECISION Powermeter on a Shimano crank arm, which may have been previously ridden but has passed all quality checks. These crank arms will fit bottom brackets using the Hollowtech II interface.

How Does It Work?
A ride ready PRECISION pod is already preinstalled on a brand-new Shimano crank arm 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 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 pods.
In The Box
Once your ride-ready PRECISION powermeter arrives, it just needs to be installed on your bike using the standard Shimano crank installation process. Connect a headunit or computer, and you can start riding with power!
Tip: If you're unsure, a bike shop would be happy to aid you in the installation process.
Indoor Training
If the weather or climate make riding outdoors tough, your 4iiii PRECISION powermeter can be used with all popular indoor-training apps, such as Zwift, TrainerRoad, TheSufferFest, Rouvy, and more. Simply use your favourite app's connection procedure over ANT+ or Bluetooth Smart, put your bike on a trainer, and get riding!
