The ATF bmx frame from S&M is the base model of all of S&M's lastest signature frames. The ATF (Alcohol, tobacco & firearms) uses S&M's standard heat treated supertherm tube set with a tapered & butted top tube for extra strength, dent resistant down tube, tapered rear stays with massive rear tyre clearance & heat treated micro dropouts. S&M says the frame is a bit burlier & stronger than most of their frames but still only weights in a 4.7lbs. section Product Specs
