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 Powermeter delivers 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 lead you to your own Yellow Jersey. Packaged into a durable lightweight design and compatible with ANT+ and Bluetooth Smart headunits, PRECISION will help you train harder and smarter.


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!

Warranty & Durability

Ridden through rain storms at Strade Bianche, mud filled cross country mountain bike races, and even tested amidst the salt spray of the ocean on Oracle Team USA’s America’s Cup competitors, you can be assured that your 4iiii power meter will be as tough as you are and is backed with an industry leading 3-year warranty. All 4iiii power meters are IPX7-rated for water immersion up to one meter and backed with an industry-leading 3-year warranty.

Chester Owens
Fantastic Meter! but I would like a higher limit on the cadence sensor

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.

Amazing products - Shipping delays on US side

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.

RH power install

Surprisingly quick and easy. All the international shipping (from UK) went smoothly and working crankset came back ahead of schedule. A happy customer.

Dual sided power meter

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.

Drive side power meter

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.
