Cycling Weekly Verdict

An accurate and consistent power meter that is very user friendly, supremely light weight, easy to fit, and easy to maintain. It can be switched between any Shimano crank equipped bikes be it 105, Ultegra or Dura-Ace. However, for those serious about training, I would suggest to invest that little bit more and get a dual sided power meter. But this is a great option for beginners using power or those on a budget.

4iiii is a Canadian brand which launched its first power meter back in 2015. Since then, it has partnered with Lotto Soudal, British Triathlon, EF Tibco SVB and even manufacturers the power meters for Specialized which have then been previously used by Quickstep Alpha-Vinal and Bora-Hangrohe.

Not too long ago training with a power meter was the perserve of the truly committed racers and those with deep pockets. The prices have since tumbled and now the tech is available at a much lower price point and a feasible option for a much greater range of riders.
