Hi Harvey,

Even though we both speak the same language...there will always be those odd words that get used in a different context.......over here in icy England I don't think I've ever heard anyone call a small flanged hub a 'low flange'....

much the same as no one would call a small frame a 'low frame'.....its either small or perhaps might be called 'little'........and likewise, a large frame would be called 'large' or 'big' but never 'high'......or as I've often seen written 'tall'.......as in 'the frame is too tall for me'.......we'd simply say its too big.

Saying that....I must admit when we Brits look at a Campag [never Campy] 'hi - lo' rear hub we [or certainly I do] call it the same as you would...hi - lo!

Fascinating stuff, I'm sure there are many other terms which mean the same thing but have different words to say so....
