PRECISION PRO

Ride Ready Power Meters
$583.99USD

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.

Used to pace attacks up the Alpe D’Huez in the Tour de France and to hammer on the Queen K during the Ironman World Championships, the PRECISION PRO Powermeter delivers industry leading accuracy and reliability when you need it most. Through our patented 3D Strain Gauge technology, you can be assured that the data you depend on will help lead you to your own Yellow Jersey.

The PRECISION PRO will allow you to view advanced metrics like left/right balance, pedal smoothness, torque effectiveness, and provide you with the most accurate power numbers during training and racing. Ridden by the top cyclists and triathletes in the world, the PRECISION PRO is the ultimate training tool to help you reach your goals.

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

How Does It Work?
A set of ride ready 4iiii 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.
In The Box
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!
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 PRO 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!
