The S&M Mad Dog Frame is specifically spec'd by the man himself, Mr. Chris Moeller. The Mad Dog frame is designed to wreak havoc in the trails or at the track with its tall standover, relaxed head tube, and longer chainstays. This trail roasting machine was also blessed with a disc brake mount setup in case you ever actually wanted to slow down.

Now featured in this 22" model makes it an ideal candidate for anyone looking to get back into riding that feels a 20" is just to small yet wants to ride at an aggressive level. The 22" bikes are just big enough to where they feel more stable to ride yet not overly large to where they feel cumbersome.
