Howdy folks.

I am a bit puzzled by the Campy DO adjuster chronology. I bought a pair from Excel Sports in probably '98-99 that were the only ones listed and they had the metal knobs. It seems however, that that plastic thumbscrew version is "newer", which makes sense when comparing the two. When did the plastic ones come along and were both types offered concurrently? About what year makes sense for the cutoff?

Thanks :^)
