>>1613638and obviously a modern claris deraileur is better than 40 year old simplex. Nobody claims that vintage shit is better than modern technology. But if you had a Peugeot PX10 and swapped out the deraileur for a modern 8-speed claris one, the bike would loose value.. That's a no brainer...
Real vintage bike looks really expensive. they are a few boutique shops in my city that have vintage bikes that look like they belong in a museum.. Obviously, somebody is buying the bikes otherwise the guy wouldn't be able to make a living.
