Ti kickstand. Epicness! So light, so strong, so kickstandy!CF is a horrible kickstand material. Great for linear loads, but not so great at lateral loads like a kickstand would be. Stresses it in the wrong places. Would you really want to risk total carbon failure while your 5 thousand dollar bike was being held up? If you are going to drop that kind of jack on a kickstand I would just go custom titanium.
