That Pista Candotti is pure sex. I love it.

For such a short commute, is there a reason you chose a SS/FG? Unless your route is flatter than a late bloomer's chest I'd suggest gears. To each their own but I can't imagine riding a single-speed for anything but pure strength training or in a velodrome.
