Change to a carbon seat post and fork and you'll not only lose weight, but a lot of the road buzz will be dampened. You can get those parts on Ebay new for very little $. If you do the fork update you might as well get a carbon stem and some regular drop bars. You'll easily drop 2 lbs. Lose the wheel reflector too. At higher speeds it will cause some bounce that can destabilize the ride. Otherwise, that's a great D.U.I. recovery machine.
