4iiii Precision 2.0 3D Power Meter - 105 R7000 - Black Customer Reviews

Delighted with price and results

I didn't think that I needed one of these, but the reducing price and the persistence of cycling friends tipped the balance. Now I'm hooked and it is an essential tool. First I have shifted from heart rate training to power and am finding huge benefits from the results. Secondly I am now using group ride apps and enjoying my winter indoor training much more. The 4iiii Precision unit couldn't be simpler to setup and use. If you have a gravel bike be careful to check the clearances. It has integrated with everything that I use and a pleasant surprise was that it clicks straight in with my Polar V650. Single side does not give me any apparent limitations in data.

I like the power meter it was a good price and works well and was easy to fit and set up. It connected to my Wahoo Bolt in a few seconds.

PowerMeter 4iiii

I was so pleased with the first one that I bought another for my gravel bike. At l last I have power figures for my off road activities as well as on road. No more Strava estimates. 5 minutes to fit and a small spacer gave chainstay clearance on my Canyon Grail on Ultegra crankset.

PowerMeter 4iiii

Finally I bit the bullet. The cheapest option was a 105 single sided left crank for my Ultegra group set. I can't say how delighted I am. My reservations about single sided have gone completely. I've adjusted the calibration to account for a discrepancy in my left leg output and to be honest it's just what I need. Fitting and setting up were super easy. Battery life seems good and it's no problem carrying an emergency back up CR 2034 as they weigh nothing. It took one spacer to give me chain stay clearance on my Canyon Ultimate. I have instant feedback on my effort and now resist the desire to go harder than I should during recovery rides. I also get an immediate comparison between my heart rate and my power and can see change over time. Why didn't I do it before?

Inexpensive And Effective

I’ve never used a power meet other than what’s built in on my smart trainer. The addition of this power meter to my outdoor rides have aided me with monitoring my effort and pacing. It works and does what it’s suppose to do. I’m happy with it.

Power Meter

I actually wanted the Stages left crank power meter, but couldn’t get one in a 170, so I went for the DIiii. So far it has been excellent. The readings seem accurate. The only issue is that I need to calibrate it every ride on the Garmin.

Crankarm power meter

Works as expected. Mounted this 105 4iii unit on my Ultegra drivetrain and it works great.

Excellent product. Great way to use power figures.

I highly recommend this product. Very easy to install on my 6800 crank and perfect connection with Garmin 520 Edge Plus. Power readings appear to be spot on (very close to my home trainer PM) with zero drop outs. Time will tell about longevity but already used in cold and rainy weather and no problems at all. A really solid purchase and at an excellent price from PBK.
