Description

ATF stands for All Terrain Frame, and it truly is. Responsive geometry that works in the dirt, at the park or in the streets. The ATF is the foundation for many of the S&M team rider signature frames, as well as a go to for S&M employees.

Easy to ride, easy on the eyes: a modern classic. 100% chromoly construction with butted Thermal-X tubing, an integrated head tube and seat clamp, a mid BB and thread on 990 mounts. Made in the USA.

Features
  • Geometry that goes anywhere. Responsive angles that work in the dirt, at the park or in the streets, which is what All Terrain Frame means.
  • Butted Thermal-X chromoly tubing. 100% chromoly with butted tubes, keeping the strength where it is needed and the frame down to 2.12 kg.
  • Six top tube lengths. 20.5", 20.75", 21", 21.25", 21.5" and 22", so you can size the frame to the way you ride.
  • Adjustable 13.4" to 13.875" rear end. 14mm 4q-baked dropout slots give you room to set the back wheel where you want it.
  • Integrated head tube and clamp. An integrated 45°/45° 41.8mm head tube, integrated seat clamp and a mid BB with ez-out punch slots: fewer parts to chase up.

20 inch BMX frame sizing

Frames are sized by top tube length. Start with your height, then let riding style decide where in the range you land.

Rider heightTop tube
147 to 157cm19.75 to 20.25"
157 to 168cm20 to 20.5"
168 to 175cm20.25 to 20.75"
175 to 183cm20.5 to 21"
183 to 190cm and up20.75 to 21.5"

The height bands overlap on purpose. If you land in two of them, riding style breaks the tie: longer for flow, trails and transitions, shorter for technical street and park. Plenty of riders, pros included, deliberately ride longer than a chart suggests.

How to measure

Top tube is measured from the centre of the seat tube to the centre of the head tube, so it is not the length of the tube you can see. Measure your current frame that way and compare.

  • Size up for stability through trails and transitions.
  • Size down if you want the bike quick and twitchy for spins and grinds.
  • Top tube is fixed once you buy, but chainstay length, stem length, fork offset and bar position all change how the built bike feels.
