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

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.

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?

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.

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.

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

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.

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.

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!

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.

Great price, quick shipping and a very happy customer!
