Re: Glossary Of Motor Bicycle, bicycle parts and tools
BGF,SBP. When I started here, I wondered what these letters should mean. There may be others.
I use no abbreviations.
True anecdote: When I was a kid, I should learn to play piano. That did not work somehow. More than one finger at the same time. So I learned typewriter. With the years it became a minimum of 250 characters per minute. So I do not use abbreviations.
