1938 Moorson Twin Tube
The Moorson Twin Tube was one of the first unorthodox frame designs, patented in 1926. With an
eye to producing a light yet rigid frame, F.E. Moorson's design brought the seat and chain stays
forward to the head tube where they were flattened and welded. This eliminated the need for lugs,
producing a strong and rigid frame that could be built with any frame angles desired. Moorson also
designed and patented an adjustable handlebar whose bend could be changed to any number of styles,
from flat to Lauterwasser bend. The Moorson Twin Tube was used by a number of successful racers
in England during the late 1920's -1930's, yet remarkably few have survived to this day, and far fewer
examples of the Moorson adjustable handlebar are to be found. This example was purchased from the
original owner in Scotland.
