4iiii PRECISION Factory Install

The 4iiii PRECISION Factory Install option allows you to convert your current left crank arm into a 4iiii power meter. Offered in the PRECISION 3 version, this factory install option is available for a variety of existing crank arms.

Here’s How it Works:

  1. After purchasing this product on our site, you will receive a prepaid shipping label along with some simple instructions in order to get your crank arm sent into 4iiii
  2. Once 4iiii receives your crank arm, using the same state-of-the-art manufacturing process they use for its ride-ready units, they will install a new power meter sensor on your crank arm
  3. When complete, your new power meter will be shipped directly back to you

 

IMPORTANT

Crank-arm based power meters attach a sensor on the inside of the left crank arm. On some bikes, there is not enough room between the left crank arm and the chainstay for the sensor to clear the frame. Therefore, you should make sure you have at least 8 mm of clearance for the PRECISION 3. Also, make sure that you don’t have a bottom bracket mounted rear brake (used on some aero and TT bikes). The important area to measure is right in the middle of the crank arm. Please refer to the image below. All sales are final. U.S. and Canada shipping addresses only.

Timing Update

Please note, due to the fact your crank arm gets sent to Canada and back, combined with install times at 4iiii, we are seeing turnaround times for factory install power meters of around a month. There is nothing we can do to shorten this timing as we are never in possession of your crank arm, however we do like to make sure customers are aware of this before ordering.

    This is the second power meter I’ve bought through this website and both times it has been a positive experience. I decided to go with the factory install for my new bike, it took less time than expected and it works brilliantly. Power Meter City is the only place I will buy another meter should the need arise.

      We really appreciate it, Steve! It was a pleasure doing business with you! Please let us know if there is anything else we can do! Ride safe!

    First I wanted to thank Josh and his staff, they are responsive, very nice and extremely helpful. After changing my mind and deciding to order the factory installed 4iiii, I received an email from Josh stating the fact that it could take a little longer than usual due to the current condition (Covid-19). After telling him that I was fully aware of the situation and potential longer time frame, I received the mailing label via email. I was expecting at least a 4 to 6 weeks time frame to receive my left crank back from 4iiii. Well, it took less than two weeks from the time I received the shipping label from Josh to the time I received my crank. To put it in perspective, 4iiii received my crank on 10/20/20 and I received my crank back on 10/28/20. I took literally 4iiii less than a week. I couldn’t be happier. I only wish all the online stores were doing business like PMC. I would highly recommend not only PMC but 4iiii as well. Thank you again, ride safe and all please be safe and respect others by wearing a mask.

      Hi Stephan. Thanks for this kind review! We also want to thank you for being a great customer. We are glad too you finally have your 4iiii left crankarm. Good luck on your future rides! Please let us know if there is anything else we can do! Stay safe!

    I ordered the factory install and shipped out my crank on August 19th. Currently it is September 6th and it still has not arrived at the 4iiii destination in Canada. I was told the total install process might stretch to 3 weeks due to COVID but it’s already been 3 weeks and my crank has not even been delivered to 4iiii to begin the install process. Very frustrated.

    • Power Meter City

      Hi JW. Thanks for the review. To be fair, this process takes well over a month as your crank arm goes to 4iii, gets installed and ships back. It looks like in our correspondence with you we pointed this out right from the very beginning. Also, please understand that Power Meter City has no control over timing of the factory install as your crank arm never comes to us – it’s in the hands of the carrier and 4iiii, which we also made clear when you ordered. We truly hope your power meter is completed and sent back as soon as possible!

    After even just 2 weeks, having this on your mtb is awesome. Reliable, perfectly hidden, no issues at all, and a great add-on for anyone, especially if you want to train more on the mtb. Can’t go wrong with this!

    • Power Meter City

      Hi Elliot. Agreed! You can’t really go wrong! – Glad it worked perfectly fine! We hope you continue to enjoy them and we are here if there is anything else we can do!
