I found this site by backtracking from a referral to my own site. It came from the "links" thread on this site. Once I was here, I thought I would register and introduce myself.
You can't get any more retro than my experience. I started riding off-road on "town bikes," old one-speeds that my roommate and I used for errands instead of our fancy road bikes. This was about 1974, and my roommate was Gary Fisher, who was not then well known outside of San Anselmo, California.
After a while we added derailleurs and front brakes to our old bikes, and then started racing at the hill we called "Repack." Unfortunately, I broke every one of my antique frames through racing and overuse, so I had to start riding custom frames. I owned one of the most collectible bikes on the planet, the second of Joe Breeze's ten original mountain bikes, built in 1978. It's now in the Mountain Bike Hall of Fame.
I'm not retro any more. I have a FS Specialized mountain bike and a LeMond carbon fibre road bike. Gary Fisher let me use the LeMond out of his bike collection after I broke my "retro" 34-year old Colnago (with Campy Nouvo Record) frame this year. I use my "retro" Ritchey P-21 for my "town bike" now.
But if you want to see a lot of photos of retro stuff, go to my site:
