In the 1930's, Horace Bates submitted a special set of Reynolds 531 frame tubes to the National Physical Laboratory for evaluation. The results showed that the tubes were almost twice as resistant to flexing as standard 531 tubes. The secret was in the way that the tubes were swaged down at each end to form an elongated arch. Bates named the tubes "Cantiflex" and in 1935 he was granted a patent protecting the design.
If you ride fast, buy the frame tubes designed to make you faster.
I have a number of tubesets for sale. These are part of the last batch of 531 Cantiflex to be manufactured. All Cantiflex from now will be made from Reynolds 631 tubing.
Set of three main Cantiflex tubes - £52.00.
