I bought a used Trek 3700 mountain bike, and the very next day started having weird issues. Anyway, I am pretty sure that the derailleur hanger was bent, so I picked up a new one of those. The guy at the bike shop wasn't 100% sure that it was an exact match to the original, however. It looks pretty darn close. Do you think this will be an issue? Also, I am not going to have a front derailleur, for the time being, because at the moment I don't have the time/money to pick one up and install it.
So if the hanger isn't an exact match to what came with the bike, will this be an issue? Also, will not having a front derailleur effect the back derailleur? I plan on not really shifting at all, until I get a front dee. I just need something to take up the slack in my chain (my chain tensioner also isn't working... I'm having all sorts of issues.)
