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!

    I am amazed. This has to be the lightest and cheapest power meter in the world and yet it gives me good clean data, without any problems. It took me three minutes to order from power meter city, arrived within five days and I had fitted it within just five minutes. I am very satisfied with this purchase and recommend this to anyone looking for a power meter.

    4iiii provide the best bang for your buck when it comes to power meters! I’ve been using the precision left side crank arm power meter for a few weeks and the experience has been great. Powermetercity’s shipping was fast and easy and I saved ~$50 on shipping instead of going directly through the vendor.

    This power meter works like a charm. Installation and setup was a breeze. Have used the power meter on several rides and the results seem to be consistent with numbers from the PowerTap I use on my other bike. I use this on a bike for which I have multiple wheelsets and tire sizes. It really works great and allows me to access power data whether I am on the road or riding gravel. I highly, highly recommend this power meter.

    I’m very happy with this power meter the installation and setup only took a few minutes. I think this power meter works as well as the more expensive unit I have on my other bike.

    I am glad that I found this site. Their products and services were in tune with my needs. I needed a good, affordable power meter and good customer service. To be fair the customer service ended up being excellent. It was easy to install and it is recording data. The rest is up to me. I have marked the site for future shopping.

    This is my first power meter and i am so happy training with one. It is as light as it can be and according to tests one of the most accurate crank arms power meters. I am glad i ordered from power meter city. I ordered it on Friday and received it on Monday with free shipping and I live on east coast I believe it was shipped from California.

    Great power meter for the price! Set up is super simple, calibrate it, and you’re on your way. The only other power meter I have to compare it against is the built in power meter in my wahoo Kickr, and they’re usually within a couple watts of each other. I was on the fence between stages and 4iiii, I’m really glad I got this one, very solid unit.

    First off, Power Meter City is awesome. I had to reach out to support prior to purchasing and they were fast and very helpful. Shipping was also very speedy. With regard to the power meter itself… I wanted to wait at least a month before reviewing to make sure I could provide the most accurate review. Removal of the old crank arm and installing the new is simple. If I can do it, you can as well. Pairing and calibrating is super easy. I have had zero connectivity issues with multiple applications. This is a solid product, priced very well, and if used properly, will make your training incredibly meaningful.

    It works as advertised. Much lighter than my previous power meter (70 grams difference). Just slightly heavier than stock crank arm. Would get a rechargeable one next time just for a slimmer profile.

    Really happy with this power meter. Its on the cheaper end to get into power meters and was a breeze to install and connect to my wahoo. Power meter city had very quick turn around time from the moment I ordered to when I got it. It was like 2 business days and it was on my doorstep. That will probably be variable upon your location, but I’m glad I wasn’t waiting weeks to get it. Very happy and will be back to power meter city in the future should I ever need a new/upgrade power meter!

    I’m a huge fan of this power meter. Relatively inexpensive, shipped quickly, and was easy to install. I’ve done about 200 miles on it and I really enjoy having power meter data for my outdoor rides. I’d recommend this product and Power Meter City to a friend.

    Purchased the R7000 for my wife as a birthday gift. She had hinted that she was interested in how much power she was producing. Although she is using a 6800 they were out of stock at the time. The R7000 works perfectly. Connected seamlessly with her Element and off she went. Very happy with this purchase.

    Really happy with this Power Meter – easy to install and integrate with my Wahoo and Zwift. My indoor training and outdoor power readings are now the same – makes training so much more consistent and results uploaded to Training Peaks for analysis more meaningful.
    High quality components, and calibration is a breeze – less than 60 seconds – the 4iiii is smaller than the cadence meter I used to run on my left crank arm – runs both Bluetooth and ANT+ connections for convenience whether your on a smart trainer or outdoors.
    Service from Josh was prompt and Power Meter City was able to organise expedited shipping at my request.
    Impressive company and products!

    Very happy with the 105 left crank power meter. I see no reason to spend extra to get Ultegra/ Dura Ace left crank that is a few grams lighter. Install takes 5 minutes and another minute for pairing. Power Meter City shipped almost instantly.

    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.

    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.
