Hi, Im new to mountain biking, and on my first time out i wrecked and bent my derailleur hanger. I can find a new one for 20 bucks. The problem is I dont know how to tell if my derailleur is bent too. I have a shimano acera which can be replaced for another 20 bucks. I dont hear good reviews about the acera, so should I try to fix it (if it is broken), replace it with another acera, or upgrade to a better shimano.
if i should upgrade, how can i tell what will be compatible with my existing equipment and what should i upgrade to?
any help will be appreciated
