Because steel is real. Old steel bikes have a character that's completely lacking in today's modern carbon fiber click bang technology. Steel use to represent the strength & technological superiority of a nation. (Would England have been able to rule the world without British steel or, could the Japanese rule Asia without the Samurai sword)? And, when you begin to understand just how many of the old steel rides are still out there it's hard not to grab a few and stash them away somewhere. I sincerely want to preserve & protect the old beauties for future generations. Especially the steel frames. (I don't give a hoot about old wheels). Now for the next question. Which steel is best: English, Italian, Japanese, USA?
