It's always funny when the Carbon Sales people login

No! progress has been made with Carbon! it is a reverse in something that was sound! some Cyclists have had Steel bikes & components for 50+ years without a failure,show me one Carbon Cyclist with the same reliability ?
Whilst we can't show what you are asking as carbon frames weren't used in the 60/70's here is some anecdotal bollox.
I have a 1980's steel framed Carlton Super Course lightweight groupset, Campag hubs and Mavic rims, lovely pearlesent white. It rides well really smooth and compliant, it is reasonably quick. I am a bit worried at it's age the forks may be internally corroded and could snap if I hit a pothole, unfortunately the aluminium quill stem has seized in the fork tube (common problem with steel framed bikes due to metal corrosion

) so I can't check. I did have a
Ribble aluminium framed road bike but the weld around the BB failed under load, so I had to bin it. My carbon aero framed bike with SRAM groupset and a choice of either 50mm carbon wheels for the flat or shallow rims for the hills is faster and 2.5 kg lighter. Not a little faster, a lot faster than my Carlton ( I have run them both repeatedly over the same stretch of road). I have raced it, tt'd it, hill climbed on it. At the moment it has clocked up 50,000 km My previous carbon frame did 10's of thousands of km as well. It never failed I just fancied a change. I don't sell carbon frames, I have no connection to the cycle industry. I did once sell a shop to a guy who cycled. Not sure if that is a conflict of interest. You can make up your own mind on that. As a chartered surveyor I do sell shops sometimes though.
Have you noticed on a cycle forum with literally thousands of members and millions of posts though that there aren't loads of threads about how my carbon bike exploded? Surely a public forum would be inundated with people calling out the industry? Have you ever owned a carbon bike or even ridden one? Or are you simply trolling.....
