This Raleigh Dynatech road frame is from the first year of DynaTech frame production. This frame was the second in line – built from high strength Reynolds tubing (equivalent to 653) bonded into aluminium lugs. The frame is in very sound condition with very good to excellent paint. These are really nice riding frames. £145
