Ron Cooper (bicycle framebuilder)  Ron Cooper (193212 December 2012) was a noted British "master" bicycle frame builder. Cooper began building frames when he was 15, starting in 1947 when he began a full apprenticeship at A.S. Gillott Cycles, London, England. He learned his craft from frame builders in England, notably Jim Collier. He was a racing cyclist selected for the national team, the R.A.F., the Brighton-Glasgow and the London Centre in the 1952 Tour of Britain (Milk Race), before an accident forced him to retire from competition. In 1967, Cooper left A.S. Gillott to build frames under his own name, and by 1970 set up a small shop in Honor Oak Park, South East London. Cooper then worked in Dartford, approx 18 km (11 miles) from his old shop in Honor Oak Park as sole fabricator, making bespoke steel frames using the traditional method of free hand brazing rather than jigs, in order to avoid stresses to be built into the frame, which calls for careful mitering and took about two days to make. Some reviews claim Cooper's frame builds provide more stability, neutrality of handling, and responsiveness.
