I was looking at the same type of wheels around 9 months ago.The Fulcrum's are a bit more bling I think, but the Aksium's still look very good IMHO. After reading a bit on the net and talking to a couple of blokes that are keen serious cyclists at work I went for the Aksium's and they have been superb, never going out of true compared to the shite Alexrims that they replaced. Then again you have experience of the Mavic's yourself so it puts you in a good position. Unless you just fancy a change that is, as there is probably little in the 2 weight-wise. Not that I know.
