I'm going to swap the stock handlebar for a riser. I've noticed the day after riding my wrists are pretty sore. Perfect excuse to go for carbon, right?
I'm also going to swap tires to ones that are a little lighter and a little more narrow. I'm thinking of going from 30c to 28c. Unsure if what I'm going to use at this time. I had Bontrager AW3 Hard Case Lites on my Cannondale and loved them, but only got them because a LBS had them in stock and cut me a deal on them. I went from 30c to 25c on that bike and the ride quality was noticeably worse, even with a carbon fork. I don't want to do that again.
