Mine is a '75 Masi, which was my main road bike in the '80's and halfway through the 90's but when I went to Aluminum/Titanium/Carbon (pretty much in that order) the Masi just collected dust (I couldn't sell it!). So, I coverted it to fixed gear, 42 x 16, then 42 x 15 which is how it is now.

Here I am with it on a century ride a couple of years ago. Note wool MASI jersey! I've ridden three centuries on it but have yet to attempt a double century while fixed. I love the ride quality of both the frame and the fixed gear aspects. Great for recovery rides after a climbing ride in the mountains!
