Hi, I'm hoping someone can help me out. I have a 1988 GT Karakoram MTB that is all original. The rear Der. is broken, so I'm looking at replacing it. I want to spend as little as possible, since this bike is just a neighborhood cruiser now. I've been looking at the Shimano Tourney line. Is there anything I need to look for in particular? I've attached a pic of the current RD, and it is a 6 speed cluster with SIS shifter.
Thanks!
