Rear Derailleur Upgrade
I have a Diamondback Outlook (please hold your laughs) for riding around until I can save up to get a decent mtn bike. Anyways, the rear derailleur got sucked into the rear wheel and is now absolutley FUBAR. It has a shimano tx31 (7 spd) derailleur, but I had nothing but trouble with it even when it was brand new. I believe its a "direct fit", meaning no hanger, correct? Does anyone have any recommendations to a decent upgrade that would fit onto this bike? My budget is $50. Thanks.
