I have been running the alligator on my XC bike since September and they work great with a BB7 and nokon housing, better power than any stock avid rotor, but one word of advice, the gold TiNi coated calipers take a awhile to bed in, the coating needs to wear down, the standard stainless are better from the start.
I just bought an alligator starlite for the front of my mod, I may run it on my SS to bed it in than transfer it back to my mod
