I'm actually fine on chipseal on my titanium road bike with 700x23 tires... doesn't bug me too badly, but I do have carbon handlebars.

On my carbon road bike, I have carbon handlebars as well... If I use my carbon wheels with 700x23s & 120 psi tire pressure, I don't feel the chip seal at all... (I could put non carbon wheels on it and see... but I think the wheels really soak up vibrations) I feel a bit "slower" just cause things don't roll as nicely.
