Gazelle? Does anyone know anything about them?

Except that the Gazelle was used by half the amateur peloton and Batavus only by one team.
And Gazelle supplied bikes to some pro teams. Okay, Batavus also, but not on the same level.
Doesn't have anything to do with the bike though, these were about the same.

Don't forget Batavus did also supply to the Dutch National team, DC. They're raced to gold and world titles. However, it is true they were not as omnipresent as the Champion Mondial in both racing as in the streets.
