4iiii Precision 2.0 3D Power Meter - Ultegra 6800

Excellent price value. Delivery is fast, 3 days to Hungary. The power meter is quick to install, and works well with garmin headunits and bluetooth android applications. The item in it was only 48% in condition, I had to replace it, but they gave another in the package. Recommended category who wants to train at a good price based on performance.

Very satisfied with Probikekit, Quick delivery, best price on the market . For the 4iii power meter shimano ultegra left arm; all I had to do is attache the crank arm to the crank and the connection to my cateye pardons SMART + was immediately ready.. I grandly recommende Probikekit for there service! Laurie

Everything works great. I am still using into it.

Easy to install and easy to pair with the Garmin. Works straight out of the box. So far have ridden the unit 5 times and power readings were consistent without and drop in the readings.

Great price on a 4iiii Ultegra left crank arm power meter. Easy to install and pair with a Wahoo Bolt. Simple, quick pre-ride calibrations. Consistent readings on tarmac and gravel. Smallest and lightest sensor of all left crank arm power meters. If you want basic power data during and after your rides, this product is hard to beat.

This has totally changed my winter training. I can target specific training both indoors and outdoors. Easy to fit and set up.

I have been using a PowerPod power meter and, while it works fine, I became frustrated with it turning off when I stopped for coffee and then sometimes not being recognized by my Lezyne GPS computer so decided to try the 4iii. I ordered the Ultegra 6800 version despite having an Ultegra R8000 chainset simply because it was cheaper. Installed easily. Recognized and paired first go by my GPS computer. Power readings somewhat more stable then the Powerpod (although overall power readings appear to be similar). The 4iii turns on quickly after a coffee/lunch break (unlike the PowerPod). I might miss playing with the Isaac software that comes with the Powerpod, but overall the 4iii fits my needs better. Recommended.

Whilst I don't own 2 cars or even one I'm happy to now have two power meters; one on my race /TT bike and one on my road bike. I've been using a Stages device which is still too expensive to replicate but this 4iiii unit is very similar and seems to give comparable readings but is much cheaper. It's on exactly the same crank model and was as easy to 'pair' as indicated to my Garmin head unit - I wasn't completely sure if there would be any conflict having 2 power meters added but it all works fine. I'm very pleased with it. The free next day delivery (Sunday) was rather good especially as the courier turned up to deliver it on a bike! - I was most impressed by that.

got this from pbk whilst on sale, bang for the buck! Love the stealth look. No more annoying rubbers from cadence sensor hanging of the crankarm, because this power meter comes with its own cadence sensor. get it while you can!

Works exactly as describes, mounts easily on both my bikes and provides accurate power data.
