    You have an octalink crankset. Here’s the [Park Tool video](https://youtu.be/cPQyQnNdews?si=Y2jd7hA6bhDiRfl2) that shows how to remove it.

    FYI, like many bike parts there will be a part number stamped on these (it’s just the other side of where the pedal screws into the crank arm. Put that into si.shimano.com and you’ll get all the info you need.
