4iiii PRECISION Shimano R7000 Power Meter

If you currently have a Shimano R7000 crankset on your road bike, this 4iiii PRECISION Shimano R7000 Power Meter is for you! This 4iiii power meter replaces your current left-side crank arm. It measures the power that is generated by your left leg and doubles this value to determine your total watts.

4iiii uses patent pending 3-D tri-axial strain gauge technology in order to achieve +/- 1.0% accuracy, which places it among the most accurate power meters available. When it comes to weight, there is no equal. The 4iiii PRECISION sensor weighs a mere 9 grams – practically nothing! In addition, the power meter features dual ANT+ and Bluetooth SMART compatibility so you can use it with a wide range of devices.

In short, the 4iiii PRECISION Shimano R7000 Power Meter is one of the most accurate, lightweight and affordable direct force power meters available!

    Super easy to browse the website and to order!! This is the second time I’ve ordered from them and will do so again in the future.

    I also had an issue with an address change as i was travelling and they easily took my destination address and used that so the item was waiting for me when I arrived:-)

    4iiii crank arm powermeters have been on my radar for a while and I finally decided to get one. It shipped fast, installing and setting it up with my head-unit was very simple. Super satisfied thus far, with a few hundred miles on it. Will likely be purchasing another one in the near future.

    Ordered a 4iiii power meter LH crank. Received an e-mail stating the unit shipped the same day and a tracking number. Arrived Friday afternoon. Had an install question Saturday and Josh responded within an hour. Thought I’d see nothing until Monday.
    Power meter installed easily and linked to my Garmin 530 with no issues .
    Great service from Power Meter City

    Great power meter. It was easy to install and is light. So far I’ve only used it for indoor training, but it seems accurate. Would recommend to a friend ????

    Just getting started with power meter. Straight forward ordering and installation process. Really good documentation online covering selection, installation, and usage. Looking forward to gets some analytics for my rides.

  8. Tim Ma (verified owner) –

    This is my first power meter and it works great. I had no problems with the ordering process (double check crank arm length) and it shipped faster than expected. There’s a PDF file online at this site that allows you to check crank/chain stay clearance too. Installation was very straightforward since it’s the non-drive side crank. Love finally having the data to train properly. I’ve probably put about 250 miles on it and it works flawlessly paired to both my Wahoo bolt and Garmin watch.

    • Power Meter City –

      Good choice on your first power meter Tim! The 4iiii PRECISION Shimano R7000 is truly an amazing power meter! Good luck on your future rides and we are here if there is anything else we can help you with!

  9. Mark Gehring (verified owner) –

    Powermeter City was great – they shipped immediately as promised and I got in a few days. Initially had some confusion as I thought a Garmin Forerunner 245 could talk to this. It will not pair, and the folks at Powermeter City confirmed that – I wish I would have asked them before I bought the watch. Also, they answered my question after only 2 hrs on a Sunday ! The watch will work if you download the CyclingDF7 or DF4 data field from Garmin IQ, but neither Garmin nor Strava will use the data. So, I bought a Garmin Edge 830, and I am very happy with everything. Not the slightest problem.

    • Power Meter City –

      Hi Mark. Thank you for this! We are glad you are enjoying them. Please let us know if there is anything else we can help you with!
