Never tried them but I race XC with these, work superb and are a great price and light.

Thanks. I've seen those on eBay. I wondered about those.
Do you use 140mm? Do you need an adaptor?

No 160 mm, front and rear (sorry wrong link). Run them with the latest XTR brakes, very good indeed.
Previously ran the XTR brakes with Hope floaters and the XTR ice tech rotors that came with the brakes. Both previous rotors were a lot heavier, no noticable performance difference (power and modulation) with the KCNC rotors once they had a few hours of riding on them.

google for Ashima - the older model with the arms pointing the other way had a couple of failures - was posted n this forum too - so as long as you fit them the correct way round you ought to be fine, but stil is a bit off putting.
rotors with huge chunks missing, such as the KCNC razor that I have (160 and 140) can cause fork judder and I find are not a effective as discs with more metal in the braking surface e.g. hope SAW.

I just ordered the Ai2 rotors to replace my third set of Airotors. The latter have been good for me -- light, excellent stopping power and no squealing. I use 160mm F/R and race XC and endurance events.
One thing I noticed after removing my latest set of Airotors -- they wore in a concave pattern, with the brake pad rounded in the middle and the rotor profile wearing in kind of an hourglass shape. Never happened on my other sets of rotors and the wear pattern couldn't be healthy (the rotors are really thin in the middle of the wear track).
Will try to report on the Ai2 rotors after I have some miles on them...

I suppose if you think about it, and this is my take on it so could be wrong, since there is less metal in the centre section, this is worn more and as it becomes thinner, the pad itself bends to where it even further.
i presume we're talking about this:

I am using promax which a slightly lighter than those and cheaper, similar to these:
they look like they is more metal in the centre so should not wear like you descibe.

I have been using them for about 4 months now with xtr race brakes. They work very well and are very light (obviously.) I have never experienced any fork shudder or brake fade from overheating.

I have those on my Niner jet 9, XTR trail brakes, never any problem, a little pulsating in low speeds.

The promax 160mm is slightly lighter than the Ai2 in 180mm
