Reviews over the

4iiii Precision 105 R7000 Left

Perfect addition to the bike to take me to the next level

Pros & Cons

Bought two, one for me, one as a Christmas present. Looks clean, easy to set up, its great for Zwift and looking back at your efforts when on the road. Also great for comparing with my mates. Everyone needs a power meter and this is such good value for money. Also easy of use compared to my old hub based PM is wonderful

Pros & Cons

Great power meter at a great price. The Android app works well for setup and calibration. Easy to swap between bikes with Shimano hollowtech cranksets (of the correct length).

Pros & Cons

Single sided power meter for a really good cost.. Once you get used to the power numbers great said for training.. Recommended!

Awesome piece of kit. And at a great price too.

Fits my Giant TCR nicely, a cinch to fit and within a watt or two of the wahoo/stages meter I also use. Mantel also been great to deal with and shipping was speedy and well communicated.

Pros & Cons

So happy with the powermeter, it’s great value with top performance Great service from Mantel. Very efficient delivery

Pros & Cons

Pros & Cons

This was far and away the best value power meter available at the time. Really easy to install and use, it works perfectly with my Garmin Edge 530 and I am already seeing the training benefits. Plus more numbers are better - always! Great product and great seller - recommended

Pros & Cons

Very accurate, great value and delivered very quickly.

Cheap to buy especially if on discount. Accurate reading easily found on Ant+ by Wahoo etc very simple calibration lean bike against a wall make cranks vertical hit calibration on Wahoo 5 secs the job is done. Battery is cheap n lasts well simple to change when needed no tools (so No fiddly tiny screws to worry about) Works brilliantly about 1 watt different to my KickR. Easy to fit Allen key to remove pedal and just need a very cheap plastic tool to remove plastic plug in end of the crank alxe, two Allen bolts to remove then pop on the excellent 4iiii crank arm tighten plastic plug with tool finger tight then fit n nip up the Allen bolts with key (or better a still torque wrench to avoid over tightening) pop pedal on.

Pros & Cons

Very easy to install and easy to set up. Love it so far! :)

Pros & Cons

First time with a power meter My training is great with this especially interval training so easy to gauge efforts Absolutely amazing

Pros & Cons

Great product and fantastic service, 10 out of 10..dispatch same day ordered. 4iiii meter no hassle calibration is great, reads 10 good to go. Can’t fault it

Pros & Cons

Pros & Cons

The power meter is well packaged. out of the box, it take minutes to fit - the battery is already installed and within a couple of rotations the power meter pairs up to the app. A quick check on the app and the firmware gets updated. Pedal away - power recorded!

Pros & Cons

Great price for this item. This is my second 4iiii power meter and during the time from my first purchase the price has actually gone down! This 105 meter is excellent value for money and is as accurate and reliable. The battery lasts well and the initial install is a breeze. Really recommend

Pros & Cons

Pros & Cons

This power meter is great it gives accurate information, will highly recommend it to anyone.

Pros & Cons

Bought this as I had been having dropout problems with another power meter. Worked fine straight out of the box and (conveniently) agreed straight off with my smart trainer. Just a no bother piece of kit to date - though I'll have to change the battery one day, no doubt! Only problem is I cant afford the RH crank meter...

Pros & Cons

This in combination with an early “dumb” direct drove power meter makes for a perfect zwift setup for less than the price of a smart trainer, with the bonus of a power meter for out on the road. Wish I’d bought one sooner.

Pros & Cons

Fast postage and the 1st meter seems to be really good and better than stages

Pros & Cons

Pros & Cons

Was recommended the 4iiii power crank by a friend , and what a good investment , so simple to set up and easy to pair with my garmin , would highly recommend this to any cyclist who is looking to get a faster , using this power crank is the gamechanger

Easy to fit and connect to my Wahoo computer. Recommend for anyone wanting data on power without spending a fortune.

I've been meaning to get a power meter for a long time now. After viewing lots on YouTube the 4iiii came out on top. Great buy.

Pros & Cons

I have flirted with the idea of a power meter for a long time but have always been put off by the prohibitive cost. I saw a positive review for this meter and googled it to find it on Mantel for significantly cheaper than I have seen elsewhere and cheaper than I thought. Ordered it late on a Tuesday and it arrived on my door early on the Thursday the same week. This during a global pandemic. Pretty impressed

Pros & Cons

If you are used to train with HR, using power will be a much more reliabe metric

Pros & Cons

Big fan of this power meter, very accurate and good value for money

Very easy to fit and set up and seems to be working well. In fact the Wahoo snap is working more smoothly. It's very easy to zero with the app. Looks very robust and adds next to nothing in weight.

Pros & Cons

have really enjoyed having more data and feedback both during and after rides

Pros & Cons

Very easy to fit and seem less set up and linking with Garmin Edge 130.

Pros & Cons

Really easy to fit, crank arm off and new one on in under five mins. Easy set up on wahooo element bolt.

Pros & Cons

Already a user of the 4iiii Precision power meter on my main bike I had no hesitation at adding a second to my new build and Mantel excelled at the price. A very good, accurate single sided power meter ideal for cyclists of all abilities.

Pros & Cons

Really helping me to add structure to my rides I know people will tell you that you can train to heart rate but if you are unsure whether a power meter is worth it just go for it. 4iiii seems to be as good as stages but at a fraction of the price. Highly recommended!

Pros & Cons

Works flawlessly from the first turn of the cranks!

Pros & Cons

Great value and reliable power meter. Have one on three bikes now.

Pros & Cons

Pros & Cons

This is my first power meter and although it is early days of using it so far it’s been great, easy to install,you have to calibrate it each time you go out which is easy done via the app and your Garmin or Wahoo etc. Nice service from Mantel and nice price.

Pros & Cons

Can only comment using it on Zwift but it appears to be accurate and a useful tool for cadence and power. A good price for a good power meter

Fast delivery and good price

Pros & Cons

Really good to get a power meter at this price. Quick to install, set up and get using.

Pros & Cons

Pros & Cons

My 1st PM. Very easy to fit and set up. Linked with my Wahoo Elemnt easily and simple to calibrate.

Pros & Cons

Very happy with this power meter, especially at such a great price. Setup instructions could be more detailed but thankfully it’s a pretty simple process.

Pros & Cons

Great power meter

Pros & Cons

Very happy, quick delivery great product works well, seems accurate and works seamlessly with my edge 530

Pros & Cons

Works as it should, easy to use and seems accurate in comparison to my other power meters. Can’t fault it as yet.

Pros & Cons

This is my second 4iiii Precision. I wanted a power meter for my second bike. My older 4iiii is Shimano 105 5800 which has performed perfectly for 18 months. The 4iiii Precision is very easy to install and is very reasonably priced. The unit itself works with little fuss which is what you want in a power meter. Another plus in my opinion is the CR2032 battery which is widely available in most local shops such as newsagents and supermarkets which makes battery replacement a easy process. Setup and calibration is simple using the app or your Garmin (GPS) head unit. In my opinion the 4iiii precision is a great cost effective way to gain the training benefits provided by a power meter.

Hassle free purchase. Postage was really fast and price was great

Good value power meter, easy to setup

Pros & Cons

xcellent service great product and great price
