The Factory Install PRECISION gives you the flexibility of having a 4iiii power meter installed onto a crank you supply.
How Does It Work?
Through our custom install process, PRECISION can be installed on a wide variety of cranksets. We’ll work with you to determine the best fit for your bike frame. Once you place your order, we get in touch with the shipping logistics. You’ll then send us your crankset, we install a PRECISION Powermeter on it, and we ship it back to you.
In The Box
After a factory installation, your crankset will be returned to you with a PRECISION Powermeter pod attached and ready to ride. Reinstall the crankset back onto your bike, connect a headunit or computer, and you can start riding with power!

All 4iiii power meters are IPX7-rated for water immersion up to one meter and backed with an industry-leading 3-year warranty.

Before purchasing, confirm there is enough clearance between your crank arm and your bike frame for the power meter pod to fit. To ensure clearance and compatibility, you will be required to send us a photo of a successful clearance-check before sending us your crank or crankset. If unsure, contact us for help.

Manufacturing & Installation
Your crank will have the pod attached using the exact tools, techniques, and staff we use on all our products, and must pass all the same high quality checks. Manufacturing should take about 7-10 business days, and you will be given a tracking link so you can follow your crank through the process.
Shipping Back & Reinstallation
Once manufacturing is complete, we will ship your crank or crankset back using the shipping method you selected at checkout. As soon as you receive it, you can reinstall it on your bike.
I would highly recommend it! I have really enjoyed this meter. It seems to be very precise in measuring power. I've used it in temps below 30 degrees fahrenheit and above 95 degrees and it has read my power like a champ. However, I like to do some neuromuscular training at higher cadences and the meter will only read up to about 170 rpm. It would great if the meter could read above 200.
Awesome products. I use precision crank PM on all my race bikes and train bike. Steady, reliable, easy to change "coin cell" battery. Just received the PM several days after scheduled delivery by the USPS. I just wish 4iiii would use ups or fedex like they have in the past.
Surprisingly quick and easy. All the international shipping (from UK) went smoothly and working crankset came back ahead of schedule. A happy customer.
I have been training with power for over 12 years using a power tap hub. Its a good device but with limited data during the ride. The 4iiii dual sided power meter works very well. It gives me data I need to hit the power numbers in my training program and it helps me smooth my pedal stroke as I recover from a hip replacement and a broken femur. I also get way more metrics to view during my ride when coupled with my Garmin 830. Its very hard to do proper training by heart rate with the lag in HR as you increase effort. Power is instant and at 64 yrs old I have seen good gains because I have the data I need to make instant adjustments.
Nach einigen Monaten exzessiver Nutzung bin ich extrem zufrieden mit dem Powermeter für XT M8000. Kommunikation und Versand absolut professionell. Versandzeit inkl. Montage GER - CAN - GER nicht mal 3 Wochen.
