Greetings,
is there a definative list anywhere that explains all the jargon used these days in cycling?
Returning after a 32 year break I"m finding I have no idea what a lot of the terms mean.
I once used a water bottle, now it seems I need a re-hydration kit.
Thanks

LOL,

how much time do you have....

Glossary. Linked. Easy.

There's a serious lack of precision and lots of just plain incorrect language usage in bicycling discussions. In some cases it just confuses the issue (referring to a cassette when the bike has a freewheel). In some cases, the same word is used to describe two quite different products (integrated headsets or sealed hub bearings). In some cases, a word is used that does nothing but lower the degree of precision (using "alloy" to mean "aluminum"). I suspect that one reason you are having difficulty figureing out what some of the terms mean is because the writers don't understand what they are talking about either.

When I graduated from Iowa State University they had a quaint requirement called the Senior Qualifying Exam. Before anyone could graduate, they had to write a 500 word essay that had 5 or fewer errors of expression. I think that a lot of otherwise smart people would have difficulty doing that today.

Ho Ho, I see what you mean and yes, thats exactly what I was looking for.
Now why didnt I think of the term "glossary"?

Wow, back when I started road biking the "cassette" was referred to as the "rear cluster". Derailleurs were made by "Huret".

I still call a "Stem" by the term I learned in the 70s -- "Goose Neck." It's the BMX kid in me...
