So my son took a stick into the rear derailleur while we were riding some single track and bent the rear derailleur. I have a newer Deore derailleur I can use as a replacement but I don't want to buy or wait for a derailleur hanger to arrive. I straightened it up with a park derailleur adjustment tool and it seems solid. Am I just being cheap and lazy, would you replace it or give it a go? Thanks. al.
