I bought a late 1980's Tommasini Super Prestige a few years back from a kid who butchered the bike by taking out the original Dura Ace components and converting it to a fixed gear. I put in a freewheel and rode the SS side for a couple of years. Never rode the fixed side. Just sold the bike a few months ago.
If this thread was started a year or so ago, I may still have that bike. This thread has gotten me keen on riding a fixed gear.
