4iiii PRECISION 3+ Right Side Factory Install

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

Here’s How it Works:

  1. After purchasing this product on our site, you will receive a prepaid shipping label along with some simply 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


Timing Update

Please note, due to the fact your crank arm 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 arm, however we do like to make sure customers are aware of this before ordering.

Common Questions and Answers

Question: How do I determine what length my current cranks are so I can make sure I get the same size?

  • Your crank arm length should be printed or stamped on the inside of the left crank arm, usually near the pedal end.

  1. Scott Myers

    This was a great solution for a TT bike that did not have enough clearance on the non-drive side crank arm. You have to pull the crankset and remove the chainrings and send directly to 4iii in Canada. The cranks w/ power meter were returned to me in about 2 weeks, faster than expected. Power meter is solid and data aligns with other power meters on different bikes. Battery life thus far has been better than my Stages. Solid product and good option for special applications like this.
