That's a good answer to the second clause, but a more specific answer is possible to the first clause, viz.:

In the pista (track) world, high flange hubs are way more common than low flange.

In the road area, it's more a matter of period. Up through the early '70s, high flange was the norm, while after that, small flange became the fashion.

Actually, if mem'ry serves, this change was roughly contemporaneous with the move from centerpull to sidepull brakes, and from fancy to plain lugs.

A digression: The abbreviation of hub styles is a slippery matter, almost as error prone as "SR" vs. "SR"*:

*One way to go is HF (High Flange) vs. LF (Low Flange.)

*T'other way is LF (Large Flange) vs. SF (Small Flange.)

Thus, the abbreviation "LF" is fundamentally ambiguous, and should generally be avoided if you value clear communication.
