The name of BSD was coined back in 1991 following a series of BMX trip videos made by a group of friends. In 1998 the owner Grant Smith put out the first product, a custom 44 tooth 10mm thick sprocket.
Fast forward to the modern day and they have a full catalogue of BMX products including BMX frames, forks, wheels, rims, stems and more along with a worldwide pro BMX team.
BSD is based in Glasgow Scotland.
