I had a Softride Powerwing 650. It took a while to compensate for beam sag and get the saddle height and angle correct. The bigger problem for me was the beam width, as it rubbed by inner thighs. This was a minor issue when riding in cycling shorts but became a major while wearing a Speedo for triathlons.
Alex Steida, the 1st North American to wear Le Maillot Jaune, competed on an Allsop for the Evian-Miko team circa 1991.
