Rs500 50/34 power meter

javidr

Hi

I have a shimano rs500 50/34 crankset and I want to install an entry level power meter. I have seen both the 4iii and the shimano stages, which are just a crank arm. However, none of them refer to this crankset as compatible

Do you know if it is compatible? If not, which power meter can I buy that is compatible with that crankset?

Thanks

Sell the rs500 and buy one that has compatibility.

The 4iii and Stages come in different versions for different crank spindles.
Your crank uses a Hollowtech II bottom bracket, so the spindle should be a standard 24mm Shimano one (first photo here: https://wheelsmfg.com/crankset-tech ) You just need to get the version that matches your crank and swap it over.

You probably want this one for Stages: https://www.stagescycling.eu/power-meter/shimano/105-r7000.html
or this one from 4iii: https://shop.4iiii.com/products/left-side-precision-powermeter-ride-ready?variant=28538691125327 (US site but I'm sure you can find it elsewhere).

Also make sure you get a crank length to match the one you already have.
