Finding a one stop shop for cycling lingo is tricky. One of the best glossaries I've seen is
Cycling Terms and Slang,

which was shared by Bilko (a.k.a. Phil Stephens) and will soon be posted on the new
Marymoor Velodrome website. It’s a great source for looking up a wide variety of words and acronyms related to road and track racing.
If you’re looking for other resources, visit the
Glossary of cycling terms post from last summer.
