SB4409

SB4409 is a rare 1981 753 Dynaflite, a Time Trial frame built from a unique tubeset called Reynolds 753 Ovoid. Based on Metric 753 tubing but profiled into oval shapes with wafer thin seat stays. This frame is a beautiful example of fillet brazed 753 tubing and is one of maybe only 25 built by the SBDU.
