i love riding my track bike, but i don't like commuting because it means the ride has to stop at some point or i've been at work all day. because of that, i'm realizing how much i love commuting... actually commuting... on my ss cross bike with fenders and rack and risers.
fenders keep me dry, rack ... well, i still usually take my backpack because it's (singing)awweeeesoooome(/singing)... and risers keep me bunny hopping curbs and aware of buses.
i honestly think a steel singlespeed cross bike like a nature boy would be perfect. the aluminum nashbar i'm on now has a magic gear(no derails yet but still) and sucks over bumps. also i think some fat slick tires would also improve the ride except for when i take shortcuts over lose terrain.
