Great piece of kit, superb value for money!

- Paul, 21 December, 2020

I already have an Ultegra 6800 4iiii power meter. When this new version went on sale at a great price point, I pulled the trigger straight away. Simple installation, easy to use and consistent, accurate power readings. My only slight gripe is that the 4iiii App can only see one PM at a time, so need to keep deleting one or the other and run a new search, in order to carry out a Pre ride calibration.

Pros & Cons

Accurate
Light

If you are into Gagets then this left crank power meter will suffice and give you good feedback during rides. One flaw is that is does not account with power meter variance between left and right crank if you use garmin product and just reads right side which is not ideal. I understand stages do not have this flaw but 4 iii looking for a solution

Pros & Cons

Affordable
Good data
Syncs with Zwift
Does not give power balance via Garmin
