Throw a dog a wishbone! And a disc brake, with a tall stand-over, but keep it light (sub 5lbs) and you’ve got yourself the reincarnated Chris “Mad Dog” Moeller frame. It only took 36 years for S&M’s Top Dawg to drop another bike custom-crafted for his breed of biking, but much like the original, its designed for dudes who want to terrorize the trails and the track and claim their territory doing it.

Engraved Shield on Headtube. Engraved '87' on BB shell. MAD DOG-tag on seat-tube
