trashzen is great, it tells you everything. i have nothing to record with that would be decent quality and i dont wanna make a fool of myself because i probably look really stupid. i can do things on either side, i tend not to though because of my derailleur and how it tends to be a magnet to walls and steps ive messed the hanger up so bad. when the tensioner goes on il properly straighten out the hanger and it should all be alot better.
