Game Changer

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

2 x power meter owner

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.

Great value, no complaints so far...

As is similar to most people who have reviewed these PM's I have been considering a crank based PM for a while. More than likely spent far too much time researching on the internet than is healthy! Anyway took the leap with this, and I am very happy with my purchase so far. I contacted PBK to ask if it would fit my bike after it failed the 'fit test'. They were not sure, and 4iiii disnt seem to think it would. Took a gamble, and it fits my giant advanced sl 2016, result. I have emailed 4iiii as a result to question the test! The PBK staff were very helpful (mainly Peter) and said I could return it if no joy. So after 2 weeks it has been easy to set up, easy to use and provides regular power measures. I am not sure how accurate vs other as I have no experience with them. I think this is great value vs another crank PM, but again no experience and its early days yet so lets see if it continues. The app set is easy to use, only downside is you have to zero each time you go for a ride, but at least you know its right and it takes 2 mins. I can swap between my 2 bikes easily too. So overall, would I recommend, definitely so far yes I would, but I have only had it for 2 weeks so there is no long term usage, reliability info I can give. Fingers crossed it continues, as it is really helping structure my training and ride efforts better through my 520 garmin.

4iiii Power

This was the best value power meter I could find. Easy to install on my existing Shimano setup. Can keep my existing pedals that I like. Having the numbers from the meter I can now really focus my training and see if my FTP is improving as a result. Would be 5* but the rubber o-ring on the battery compartment was missing. I have contact the 4iiii support who are being a bit slow in sorting it out. So it is only suitable for going out in the dry at the moment. You get a spare battery which is a nice touch and really easy to swap when the time comes. So overall I am happy with my purchase and feel I made the right choice.

Perfect training and racing tool

One year ago I wanted to acquire Stages power meter. But price was too high for me. And I was waiting for something cheaper, but with high quality and precision. 4iii Precision 2.0 3D power meter matched all my requirements in theory, and now in practice. I'm very satisfied with this product. Sometimes long waiting rewards!

Nice product

I bought this to help me train over the winter ready for next season's TTs, and to help me dose my effort better. I wanted a left hand crank as I wanted to transfer across bikes - onto the TT bike in races, the summer bike for training, the commuter and turbo in the winter. Pedals are too expensive for me, and this is the cheapest of the crank options (and well reviewed by DC rainmaker). You can never tell how accurate the meter is (unless you calibrate it yourself against another perfect meter) but DC rainmaker seems to think it is no better and no worse than any other. The main criterion for me was ease of transfer from one bike to another, and it is dead easy - release the two bolts, unscrew the tension cap and it comes straight off. No more than 10 minutes tops to move from one bike to another. Pleased with this purchase so far.

Good Value

Great tool for everyone that wants to measure up efforts. Easy setup and integration with strava.

4iiii Power Meter

Well - what can I say, I bought this as a second meter, having already fitted a Stages single sided crank to my "main" roadbike... Of course, when you get used to riding with a power display, and use it for pacing, training etc. it's annoying to either have to keep swapping the cranks to the 'cross bike or riding without the information. So, I decided I wanted a second meter. And, having already had "issues" with water ingress on the Stages (that necessitated a replacment - though this was before the "new" mk2 enclosures - so i've still got one of the old square Stages units with the fragile battery door) I decided to try a different supplier - the 4iiii fitted the bill - cheaper than the Stages, and a friend had been running one of their cranks for a full Welsh Winter without it blowing up, so I thought "go for it" I've only had the unit a couple of weeks, but so far it's been fine - the power readings have been "sensible" compared to what I'd expect with the Stages - it's not had any wierd "spikes" in the readings, and of course, it went onto the bike simply and without any drama. I'll probably drop back in here and add a second review in a few months, as I'm borrowing a pair of powertap pedals for a couple of weeks while a friend is on family holday, which I'm hoping to use to a) see that the power readings compare directly between the 4iiii and the Stages and b) see if I have any major imbalance from Left/Right that the 4iiii can be used to compensate with - if that's the case, I'll probably sell the Stages on and get a second 4iiii unit...
