Agreed.

Sort of. Also important to note that there is no "trollness" going on here.

I totally understand that this could easily veer into some off topic unpleasantries. But the very nature of this discussion easily falls within the timeline. But, if the rules are to be followed to the letter of the law, not the spirit, then this topic should have been moot from the onset.

My opinion is simply this- the question involves both OT parts and ideas. I agree that the part about using modern shifters veers a bit, but I believe the spirit is still very on topic. Not to mention if the idea of the "garage chat" theory is still in play, it's natural for a conversation to ebb and flow but still keep the nature of said conversation. One would not simply stop talking about something because it's slightly beyond the initial scope of the conversation.

But I digress. My original question was more of "this has got me thinking/excited to try something different" than purposefully delving into OT land. So in the interest of "keepin' it real". I'll drop it.

While the CR focus is on the beginning of the twentieth century to 1983, a few contemporary, classically made small workshop bikes are considered on- topic* here These are generally referred to as "KOF" (see # 2 above). Those welded, injection molded, or glued modern wonders belong in some other mail list. Ditto for mountain bikes, "middle weights", BMX, recumbents, and balloon-tired bikes. Those bikes have merit, but they do not belong on the Classic Rendezvous. Ditto for components that are post- 1983 or those which are harbingers of a new, aesthetically "modern" era (like cycle computers, clipless pedals, index shifting, etc.) If in doubt of the appropriateness of your intended topic, please ask the web master first."

I found this surprising in that every good index derailer is a slant parallelogram, while the early 600 is not. Conveniently, it even came with a barrel adjuster.
