[QUOTE=Nightdiver;18106386]As a rather pricey alternative to the above two suggestions, the Mu is a perfect candidate for a belt drive.

Regarding Nightdiver's suggestion, I run a belt drive on my Mu and really like it. It is so nice not to worry about grease & grim or lubing the chain. The other day I was reminded how much I like belt drive when I had a flat on the rear of one of my chain drive bikes. Even though I tend to keep my chains wiped down and clean, plus carry disposable gloves, it was a little messy repairing the flat along side the trail. Compared that to a few weeks earlier when I had a rear flat on my Mu and had no greasy chain to deal with.
