My perfect commuter keeps evolving. I started out riding a De Bernardi steel lugged bike because that's what I had available. I also used my Merckx Corsa on occasion. Soon I began to want a bike that could handle fenders, larger tires and a rack, so I got a Bob Jackson World Tour that I rode for a couple of years. The touring bike felt heavy and slow after a while, a bit of overkill for commuting, so I replaced it with a Salsa Casseroll. Rode the Casseroll for a couple of years and replaced it on whim with a Gunnar Sport. The Gunnar was great but I started missing the stopping power of canti brakes, so I just recently replaced it with a Gunnar Crosshairs. Maybe the Crosshairs will be my perfect commuter?
