I just bought some Bontranger XXXL Carbon Clinchers. I have a friend who raced on them and had nothing but good things to say about them. He sold his to a friend and told me it was a big mistake and he would buy them back if he could.

I've only ridden mine 200 miles or so but really like them so far. I use them for every day wheels as I don't race. The braking is good with the cork pads supplied with the wheels (I haven't rode in the rain yet, but live in AZ).

I can certainly tell the difference in acceleration but both the bike and the wheels are lighter than what was on my previous bike.

I was also looking at the Dura Ace C24's but since I was buying a new custom bike I figured I might as well go all the way.

Good Luck with your decision...
