Very nice. I have a CAAD 3 that I turned into a fixie when the shifters broke. It was cheaper to do the conversion that buy new shift levers. My club does all of their rides from October 1 to January 1 as a group on fixies using 65 inch gears to even the playing field. The routes are a combination of flat and some serious climbs. A lot of fun, and, as you say, great for the track. There are days when I wish it was a single speed instead of a fixie, but then again, the downhills really promote leg speed!
