Blockchain

For everyday bikes block chain was pretty much out by the 1920's, as roller chain ran quieter and with a bit less friction.

It held on for track racing well into at least the 1960's, probably early 70's, and some suppliers had old stock parts as late as the early 2000s.

Personally I love the gentle clacking sound it makes.

Me too!!

No virtual blockchain for me, thanks anyway and good luck to all who love it.

And I am not dismissing the fact there are a LOT of fakes and repros of almost everything, circulating as real? in the hobby.
