Have you gone through a Raven yet, just wondering what mileage you got out of the rear. I am estimating only 3,400 miles out of the one I have on there now.
I didn't write down my exact mileage when I put it on, but I am at approximately 3700 miles. I currently have about 2 mm down the center and 3-4 on the sides from all my commuting and lack of twisty road running. I am shooting for another 1000 miles out of them, as long as I can spend the majority of the time leaning instead of slabbing it.
I will say that the wear on the Raven is much more uniform that with my PR2. The left and right sides are nearly identical. The PR2 showed a huge difference between the right and left side.
