Phillip type curve bar bicycle frame, model SC-F-105, a step-through frame with a curved main tube and brazed up lugs and shell, offered in 18, 20, 22 and 24 inch sizes. As the main structure of a bicycle, the frame holds the fork, wheels, crankset, seat and handlebar. A curved upper tube sweeps down from the head tube to the seat tube, with a straighter tube below it running to the bottom bracket shell, giving an open, low entry. Seat stays and chain stays form the rear triangle. The finish is dark, with orange and yellow decals.
