(The ended up going with a combination of stamped aluminum and hydroformed aluminum tube, and built and tested a couple parts, before the program was canceled).

There was another BMX cvompany in the late 70's early 80's named I believe VITUS they manufactured Aluminum BMX bikes which were glued together using forged or cast connectors with T6 tubes if not mistaken. EXTREMELY LIGHT and strong.
