A new project... A 1981 SBDU Special Build. There aren't many of these, a Dynaflite TT built with 753 Aero tubing (SBDU called this Ovoid). Ignore the current 753R transfer, as all the current frame transfers have been fitted later. I'll be fitting the correct transfers soon.
Forks are standard SBDU 753 wide oval blades with a Cinelli SC crown
The Dynaflite had to be Fillet Brazed because of the shape of the tubes - fillets formed with Silver Solder and with reinforcements add under the tube join.
Head tube has a reinforcement ring at the base to stop the tube spreading.
The seat stays are flattened and ultra thin at the rear ends.
The seat stays are fastened to small reinforcements directly on the back of the seat tube.
Trying to show the width of the seat tube is difficult - the seat tube is the same width as the clement seta tub on the rear wheel.
This frame has been built specifically for TT with a single rear gear lever boss and no front mech braze on fitting - so it will need to be a single chain ring build.
