yan- Didn't one of the earliest shifting systems involve reaching back and
opening the QR, then using a fork sort of thing to push the chain on to
the next cog?

Wouldn't this work on a fixie? BRBR

Yep, Earliest Campagnolo 'shifting' system, bring yer checkbook if ya find one
and learn to play the piano-

Why not just weld a freewheel together, add as many cogs as you wish and then
stop to change the gearing, must have LONG dropouts for chain tension tho-
