Description

4iiii PRECISION Shimano Ultegra R8000 Power Meter

Introducing the all new 4iiii PRECISION Shimano Ultegra R8000 Power Meter. 4iiii has combined their patent pending 3-D tri-axial strain gauge technology, measured at +/- 1.0% accuracy, with Shimano’s best of breed Ultegra R8000 groupset. The result is one of the lightest, most affordable and most accurate direct force power meters available.

The PRECISION determines your total power based on the force that is generated by your left leg. This left-only design allows for a power meter that is lightweight and easy to install. Specifically, the power meter adds only 9 grams to your crank arm and is installed in about 10 minutes. In addition, the PRECISION is compatible with both ANT+ and Bluetooth SMART devices. This means you can use it with your favorite bicycle computer, watch or smart phone.

    Works perfectly! No issues with the unit and super easy to use. I’m using with Wahoo bolt and is seamlessly easy. Had an initial fitting issue with frame clearance but Josh was super helpful and I was up and running same day. I wish more businesses were this way.

    After watching countless YouTube videos and read many reviews, I decided the 4iiii was to be my entry into the power meter world. I made a great decision. Installing was easy, and syncing it to my Garmin edge 520 was trouble free. Synced the meter to the 4iiii app, and done. First ride I was getting readings all over the place. Then a friend suggested that I only use it for a 3 second power average. That was what I needed. I was looking for similar readings to what I see on my smart trainer, while using zwift. Really happy with my purchase.

      Hi M. Thanks for dropping us a quick note on your 4iiii. Yes, 3 or 5-second power smoothing is definitely the way to go! We hope you continue to enjoy it and we are here if there is anything else we can do.

    I’ve been using the 4iiii precision r8000 for about a month now and have logged 2k Mike’s with it. It has been flawless! I did several comparisons to its power numbers benchmarking against my wahoo kickr and it has been +/- about 2 or 3 watts which for a single sided unit for $350 is great to me. Also it is very easy to install and to calibrate. If I had to say one criticism it’s that it would be nice if it had an auto zero feature because sometimes I have forgotten to do the zero offset calibration pre ride. Other than that it’s great I would highly reccomend also side note shipping was very fast 2 days which was awesome!

    Couldn’t have been easier to sync with my wahoo and get on the road! Based on my experience with other power meters, this has been very accurate, great battery life, and handles well in weather. Now it’s on me to get my FTP up! Already looking at other 4iiii for my other bikes!

    Power meter works great and it was cheaper than what I saw other places online. Customer service was top as well. They even called to make sure I had selected the correct one and had it shipped out same day.
