I use a '06 Schwinn Fastback 27 for my commute. The bike weighs 22 pounds and came with Tiagra shifters, front dérailleur and 105 rear dérailleur. The bike has nearly 9k miles on it and the only things I've changed because of wear and tear are the chain and the tires. Besides commuting I've used the bike for century rides and some group rides. I've been very happy with this purchase and have received multiple compliments regarding the bike's looks.
