So I just got the bike back from TK, putting Hoopty's tires on, and Bart told me that I need a new chain and sprocket.

I've heard everyone say 520 conversion all over the place, but I've never heard why I should do it.

I'm looking around eBay and I can get a chain and both sprockets for around $140 or so. Good Deal??? ebay 520 kit

Basically, should I just go ahead and get this????

Thanks,
