Specialized made a composite and carbon fiber version. Personally, I'm not too excited about rocking full carbon wheels on the street. I used to have a trispoke wheelset (which I got for really good deal) but didn't like being constantly paranoid about them when riding over less than ideal roads. They look cool (but I didn't like all the attention I was getting from them) and make a cool sound, but really are not worthy of anything else beside racing. Spend your $ on something more useful.
