Yeah, nice chain guards. I live in a very hilly city, I need my triple chainrings for commuting. The big, long, steep hill climbs every day would kill my knees on a singlespeed. Believe me, I tried for a few months, and I did hurt my knees. And that was with a 42:20, which was too still too high on the climbs, and way too low for the rest of the trip.
