S&M Passero Signature Whammo V2 FrameWith a shorter back end (12. 9"), taller headtube (5") and raised bottom bracket (11. 8"), the Whammo V. 2 will have you shouting Wham Bam, thank you Man! The taller headtube (ie. less spacers) translates into a cleaner setup, the shorter back end makes it more responsive and the higher bottom bracket improves sprocket clearance when grinding. The rest? Tried and true from the first Whammo. ###section### Product Specs MATERIAL: Chromoly ThermalX
