I'm a newbie on here but not to the love of bikes. I've been at home a lot recently and this has promoted my love of them and allowed me to do a couple of restoration projects which I have thoroughly enjoyed. This was also promoted having read Rob Penns book, it's all about the bike. I'm not a diehard cyclist like friends who take part in triathlons and iron man comps, I'm a designer and its the history, architecture, grace and evolution of the bicycle that really seduces me. This has lead me onto the question I want to ask. I have searched the internet for the answer with no luck yet.
The seat cluster is a fascinating part of the bike, when did bike manufacturers stop bolted seat stays and move to welded seats stays? Looking at many frames online I guess around the 30s but any other knowledge and input very welcome.
Cheers!
