I have trouble believing that a Cannondale R2000 is all that much heavier then much anything else. You could go on a weight-weenie craze and make it lighter, but I doubt it would make much difference in your climbing ability. As you said in another post, you weigh in at 195. You apparently are a really strong rider, but that's still a lot of weight to be dragging up mountain passes.

If you find a bike that inspires confidence on high-speed descents on crappy roads, let me know. New England is full of them (as you might have just found out). Meanwhile, I'll just keep my descent speed slower then my guardian angel flies.
