Frank,Those gears and chain I was trying to remember were in fact "Sachs"as
in Gunther Sachs.They were much less expensive than Campy,who I believe
finally bought them out.I must dig up a photo of me in my younger days
riding the "Specialised"carbon fibre racer.Mind you it was still a
"Veterans"(over forty) Sunday morning race near what is now the Olympic
site.I came third in one of them!Nothing like the sound of "whoosh""whoosh"
from behind you(everybody standing up and pedalling like crazy) as you are
nearing the finish line and suffer the disappointment of being overtaken by
craftier rides than you.
