My commuter at home is a 1996 Specialized Ground Control A1 with a Quadra21 Rock Shox upfront. I honestly don't think you'll notice the extra pound because of the suspension, especially if you're moving almost 50 pounds around town. It will definitely be a good workout, I know it is with my full suspension bike, especially if I have to fight any headwind......makes riding my Addict feel effortless.....
