I am anxiously reading all the threads I can in order to learn more about bicycles and biking. I keep running into terminology about that I don't understand like 36h 40h? What other terms do you use to describe hub size, rim size, wheel size, et? and what does freewheel mean?
I tried searching on these terms and keep coming up with posts that use these with no description or, with google, articles that use these with no description.
