I can't work out if some of the comments in this thread are full of bigotry or irony.
I currently only ride steel road bikes, I would quite like a carbon bike at some point, as they are so incredibly light; my son's Boardman Procarbon weighs nothing in comparison to my lightest steel.
As for buzz, you can get that on a steel bike thank you; my Raleigh 853 on rough roads is far from a joy to ride, and occasionally it is just as well to check any fillings in my teeth, to make sure they are still there. By comparison, my Concorde (made of Columbus Alle R) ridden on the same roads is noticeably smoother.
A 'serious' cyclist friend of mine told me that a carbon bike is worth two minutes up the Cheddar Gorge. He lives in Cheddar and rides the gorge on a regular basis to get onto the Mendips; over numerous rides he could see that when climbing the gorge he was always two minutes faster on his carbon bike, over his steel bike. He doesn't put this entirely down to weight, more down to the directness of effort to drive, as he put it "everything I put into the pedal gets to the back wheel".
As for lycra; I wear it on all my bikes, road and mtb, as it's the most comfortable and practical clothing to wear. Let's face it, at my age it's tough enough climbing hills in lycra, if you lot think I'm going to put on tweet and wool just so I 'look retro', you can think again.
Vive la difference!
