But I'd like to ask what everyone thinks of (I forgot what it was called) red plastic chain tension cog thingie on the rear derailleur? I'd think it would lose it's teeth pretty fast but would it hinder movement? or would it not even matter?
A deraileur cog is a deraileur cog is a deraileur cog. So long as it's made of quality materials, it will serve you well.
Note that most of these cogs are plastic. Metal cogs are pretty much no longer in use....plastic doesn't wear on the chain as much.
