It's a good idea to change out the cassette when you get a new chain (if it has a lot of wear that is) as well. Like most Midwest riders I'm guessing you spend the majority of your time in the middle chainring. I'd just change that one out if it's that worn. Do the cassette first and see how it feels then. Changing out the cassette is a good way to loss weight on your bike anyway. Here's a XT on sell: http://www.jensonusa.com/store/produ...+Sprocket.aspx
