Advanced tip is to remove the derailleur hanger and see against a flat surface wether it’s straight or not. If not, and you don’t have the calibration tool then just clamp it on a vice and use hammer/pliers/crecent wrench to bend it back straight. It’s not going to be perfect but since it’s already bent you’re probably not going to make it worse either.
Thank you! I need to adjust mine, this is great advice!
