GB stands for Gerry Burgess, not Great Britain, as so many of us baby/bike boomers thought. GB products were regularly used on British-made bikes such as Raleigh that were exported to the U.S.

Burgess began making bicycle components just after the Second World War. Early production did not measure up to the quality of continental manufacturers, but in a few years, GB had a wide range of decent parts.

The company made both sidepull and centerpull brakes, stems, bars and toe clips.

The GB Synchron brake was ahead of its time. It was probably the first dual-pivot caliper. After GB went out of business, the German Altenburger company made it for a few years.

GB went out of business sometime in the 1980s.
