Improve training performance with a 4iiii Precision 2.0 3D 105 R7000 Power Meter. By employing 3D power meter technology and a triaxle strain gauge on the crank arm, this 4iiii power meter measures the amount of power you're putting through the pedals to +/-1% accuracy, so you can ride harder, faster and further.

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.

4IIII power meter.

Wasnt sure about the power meter but decided after christmas to invest. Using it together with garmin530 and Training Peaks to improve my training. Before this was doing a load of junk miles but with darker days I use it more for indoor training and to increase strength and cadence Easy to fit. Linked to garmin easy enough and away you go... Great investment, cheapest out there and effective for my needs.

Exactly what it says on the tin.

I've bought 2 of these for the winter bike and my race bike and they're spot on. I highly recommend this product. The factory reset is a handy tool and is sometimes required after changing the battery. I've had no issues with them and the support from 4iii is excellent if ever you need it. Reasonably priced and accurate readings. Quick and easy to link to Garmin and battery lasts for ages!

Brilliant and Cost Effective

Easy to install and connect to cycle computer. Yes dual sided would be nice but this is a fraction of the price and all you need for targeting Power Zones on training rides or to pace yourself. Particularly useful for recovery rides so that you can ensure you are riding with low enough power to make the ride effective. Riding with Power has taken my training and riding to the next level, and the 4iiii was a cost effective way to achieve this.

Crank based power meter

Great price, quick shipping and a very happy customer!

Solid and straight forward

I purchased this on Black Friday as an early gift to myself. It's honestly straight forward and will require the preload cap tool to install. It's been solid and accurate so far after a month's use. It primarily resides on the bike reserved for the trainer but no reported issues outside either. The 4iiii app works well and makes calibration easy. Otherwise the only issue I've had is dropout in Zwift but it appears to be with the application rather than the device as it coincides with HRM issues as well.
