4iiii PRECISION Dual-Sided Factory Install

The 4iiii PRECISION Dual-Sided Factory Install option allows you to convert your current crankset into a dual-sided 4iiii power meter. Offered in the PRECISION (CR2032) version, this factory install option is available for a variety of existing cranksets (full list below).

Here’s How it Works:

  1. After purchasing, we will send you a 4iiii Factory Install box along with a prepaid shipping label for you to mail your crank into 4iiii
  2. Using the same state-of-the-art manufacturing process 4iiii uses for its ride-ready units, a new power meter sensor will be installed on your crankset
  3. When complete (usually around two weeks), you’ll receive your original crankset with power meter installed right back to your front door



The 4iiii Factory Install is available in both the PRECISION model for the following cranksets:


  • DURA-ACE FC-9200
  • DURA-ACE FC-9100
  • DURA-ACE FC-9000
  • Ultegra FC-R8000
  • 105 FC-R7000

Please confirm your crank arm/bike has clearance for a crank arm power meter by checking your frame clearance. All sales are final. U.S. and Canada shipping addresses only.

Timing Update

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

    First off, Power Meter City is awesome! They went out of their way to make sure the power meter would fit my bike and to make sure I was taken care of after my power meter was delivered.

    And then I was hesitant to buy a dual-sided power meter for my Shimano 9100 cranks, based on negative reviews about those cranks on various web sites. A simple phone call to the 4iiii engineers about those issues and I was able to conclude that 4iiii has its act together. A truly accurate, reliable power meter at a competitive price – you can’t go wrong!
