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.
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.
Quick, easy and simple!
If you want to be able to gauge your efforts with out busting the bank this is the power meter to get. Easy installation that any one can do.
Simple right out of the box
First of all this has got to be the cheapest power meter on the market and ProBikeKit always seem to honour discount codes on most product! Straight out of the box it’s super simple to install and calibrate then you are out riding. Works first time now messing around. Couldn’t be happier (unless my FTP was higher). Thanks 4iiii and PKB!
Budget meter value for money
This power meter is great for weekend warriors such as myself who just want to track their power output in general and not too worried about training for Cat 1 races. It's super easy to install and easy to record power output from any ant+ device. I have used it with both Fenix 5 and Edge 530 and works like a charm.
