The ATF bmx frame from S&M is the base model of all of S&M\'s lastest signature frames. The ATF (Alcohol, tobacco and firearms) uses S&M\'s standard heat treated supertherm tube set with a tapered and butted top tube for extra strength, dent resistant down tube, tapered rear stays with massive rear tyre clearance and heat treated micro dropouts. S&M says the frame is a bit burlier and stronger than most of their frames but still only weights in a 4.7lbs. ###section### Product Specs MATERIAL: Full 4130 Chromoly HEAD TUBE ANGLE: 75° SEAT TUBE ANGLE: 71° CHAIN STAY LENGTH: 13.4\" BB HEIGHT: 11.7\" WHEEL SIZE: 20\" STANDOVER HEIGHT: 8.5\" DROPOUT SIZE: 14mm HEADSET TYPE: Integrated BB TYPE: Mid BRAKE MOUNTS: Removable GYRO TABS: None WEIGHT: 4.7lbs ###section### Product Highlights Nuetral Geometry for responsiveness and stabilty Great all round frame for all types of riding Top Tube gussets with butted tubing for added strength Dent resistant downtube Made in the USA ###shogun-image-section###
