'm surprised a 2001 bike came with a threaded headset. Anyway I went to threadless on one of my older bikes. You'll find a considerable weight savings. The CF fork gives a much better ride. I've tried CF bars but noticed little difference in ride quality over Al. But CF looks cool.

I've never had a bad experience with anything brought from Performance. Their return policy is excellent so I doubt you will ever have any regrets.

As someone else said, just go for it. You'll enjoy the upgrade and you can't beat that price.
