Made in USA
CNC’d from 7075 aluminum for strength and style
15/16” (24mm) center bore (19/22mm steel hat washers included)
Integrated guard for chain protection can be run inside or out
4 rotation positions
Plenty of guard clearance for popular half link chains
One hundred percent American-made, the Scumbag 7 Series is carefully crafted from Vari-Wall THERMLX tubing and features a short rear-end, thick drop outs and angled Thread-On brake mounts for a straighter cable pull. With its 9″ stand-over, slightly taller 11.8″ BB for crank-arm grinds and more predictable 75.3° head angle, Brandon Begin’s Scumbag 7 Series frame pairs beautifully with 7up-inspired BEGIN 4PC bars. Order today for a pairing that goes down smooth in the streets.
