Howdy folks.
What is the timeline for the steel knob tipped dropout adjusters vs. the plastic tipped ones? I would have guessed that the plastic is/was the newer version, but I bought a new set in about '99 from either Excel Sports or Co. Cyclist and they were the steel tipped ones. I have also seen pictures of early to mid-80s bikes that have the plastic ones.
Thanks,
