Here's my bike which I use for commuting. Diamondback Copperhead (circa 2007) with rack & SPD pedals. Front tire: Continental Touring Plus. Rear tire: Continental City Contact. Just about everything has been repaired, replaced or upgraded at some point. Only change since this pic are the studded tires. It's gone through 3 years of 3 season commuting. This is my first winter of commuting so we'll see how the bike survives.
