Great Power Meter

Great power meter. The only downside is that it only measures left side and doubles it. However, it is simple to set a correction factor to account for left/right imbalance. Once the correction factor is set the overall power is very accurate giving very similar readings to my spider mounted power meter

Pros

  • Price
  • Weight
  • Easy to change between bikes

Cons

  • Left Side only
  • Only compatable with Shimano Hollowtech Cranks

Simple and effective

Its my second 4iiii power meter after my first one went faulty. I have to say its easy to use and fit but also extremely good value for money in comparison to other products. The App is intuitive and simple, connectivity is very simple and the feedback for your training via a third party software is great. It has really revolutionised my cycling at what is really a professional level product. Given professional teams use it at World tour level it cannot be bad. The highest accolade i can give is that although i had one break on me i bought another to replace it.

Pros

  • Simplicity
  • Lightness
  • cost
  • unobtrusive
  • fitting
