Just a interesting value question. On vintage older road bikes why do so many people consider downgrades like Single speed or simple 1x gearing, or ugh strait bars upgrades. I have had some great classic proper road/sport bikes seem almost unsellable while a iffy single speed sold in 3 hrs. Here are some examples with pics OK rebuilt 64 Gintane with rack took a couple of months to sell at the dirt low price of $200.
While not so great downgraded bikes like this Itoh conversion 7 speed sold in a couple of days for the same price.
Or this thrown together Fuji as a single speed which sold in 3 hrs.
