Recommend a rear derailleur, please. needed urgently.
On my way home from work today, my chain started binding. I backpedaled a bit but the problem didn't go away. i pull over and see that i've lost one of the cogs on my rear derailleur. I spent a good 15 minutes trying to hunt it down but didn't have any luck.
Suddenly I'm derailleur shopping.
I have a mountain bike with all shimano components that i use to commute to work. Its a 21 speed so i need a 7 (or 8?) speed derailleur. The previous derailleur was a Acera. The only 7 speed that nashbar has is $6 - I think I want something better.
What should I look for? What do you recommend?
rear - 12-28
front - 22-44
