The Avid G3 Cleansweep rotor is the fruit of this labor. It featured varying sizes and shapes of cut outs for a more consistent feeling braking surface and vastly improved heat dissipation. The G3 also sheds approximately 10g over the G2 Clean Sweep rotor design. Available in 160, 185 and 203mm diameters.

Bottom Line:
Like most rotors from Avid, it was warped from the start, and needed truing. I spent an inordinate amount of time trying to do so. I have always been able to true the 160 mm rotors in the past. This one was a 185 mm rotor, and I spent all afternoon trying, no luck. I missed out on 2 rides so far this year because of warped Avid rotors. I am a machinist by trade, and I only machine stainless steel at this time. The runout (I used a dial indicator) was terrible, there is no way these would work without rubbing on the brake pads on either side. My guess is that they got too hot in production. When I buy a high-end product I expect that I won't have to "tweak" it myself . But every rotor I've gotten from Avid over the last couple years has been of a poor tolerance, and is not something I would I would send to QC myself.
I used high end wheels with all rotors, and even swapped wheels to make sure it wasn't the hub facing being the problem.
I'm getting rid of these rotors soon and going with another brand. I like the calipers that came with them (Avid Elixir CR's), but I will likely go with another brand entirely because because I'm tired of Avid. I wish I could give all Avid rotors less than one chili.
