Robert, there are a MILLION things you can do. Here’s the short list:
EA70 Zero seat post

1. Get rid of the shock fork, and replace it with a nice rigid aluminum fork for around $170.
2. Get rid of those heavy Ritchey wheels and buy a pair of Rhyno Lite XL wheels鈥$50 per rim, plus having your old hubs re-built with them (another $200).
3. Get an EA70 Zero seat post ($90).
4. AND get a XTR crankset鈥攙ery light, and only $675.
5. Finally, swap out that heavy frame for a nice, light Blur LT frame鈥攐nly $1,400.
See where I am going? Really, there is hardly a thing you can do. The fork and wheels, maybe. After that, you are much better off buying a new bike. You can’t take a pig and make it a greyhound without a lot of very expensive modifications.
So just bite the bullet and buy a city bike. ‘s Novara Big Buzz ($800) is a great city bike, with an聽 aluminum frame, straight alloy fork, grip shifters, and 18 speeds. Fast, but tough enough for the brutal potholes of West Virginia roads. Or try a聽聽Escape City ($540). It’s based on a Giant mountain frame, but has the specs for city riding. Great price, light and tough. Or try a 聽San Anselmo ($645), another bike with an aluminum frame and plenty of street-smarts.
So you see, for less than it would cost to lighten up your Cannondale, you have a lovely city bike. So go forth, and ride.
