Stages Power L review

The Stages Power L Shimano 105 is a single-sided power meter that replaces the offside crank arm on your bike. You pull off your existing crank arm and fit the Stages Power drop-in replacement to get some power measuring data.

Stages produce a full range of different versions for each groupset, so you need to match the correct one. In this case, my bike has a Shimano 105 groupset, so I needed that version. As it is the offside crank arm, chainrings are not important, but if you want the dual-sided one, you will need to match your chainring as well.

The beauty of them is that they plug in and go. You don’t need to change your pedals, and if you are comfortable taking it on and off, you could even swap it between bikes (if you had another with the same groupset).

The unit transmits on both Bluetooth and ANT+. In the past, there have been issues with drop-outs between Garmin and Stages. I haven’t experienced any of this; it has worked perfectly with my Edge 1030 and with TrainerRoad on my iPhone. I have had some drop-outs on Zwift, though, but I’ve had a lot of problems with Zwift regardless of setup.

Battery life is reasonable. It takes a 2032 watch battery which has lasted me about six months. The battery is easily accessible so looks simple to change.

Without calibrating it against another power meter, it is difficult to say how accurate it is. But, on the turbo trainer, it has worked like a dream. Outside has mostly been fine, too, although I have occasionally got spikes of power way higher than I would expect.

I’ve also had a bit of squeaking. Whether it is because the crank arm has come loose or because there is an issue with the bottom bracket on my bike is not clear.
