S&M ATF BMX Frame Description:
The S&M ATF Frame was designed for excellent performance on the trails and in the park and streets. The All Terrain Frame (ATF) was made in the USA by S&M from Super Therm tubing. It features an integrated headtube, top and downtube gussets, externally machined Mid BB shell, integrated seat clamp, tubular stay bridges, tapered seatstays with bosses for removable U-brake mounts (sold separately), and 5mm thick dropouts. It's no surprise why the S&M ATF Frame is one of the most popular frames around.
