OK, thanks. I haven't noticed any problems with the performance of the brakes. Sounds like it's no big deal; I was just a little concerned to see the difference between the rotor wear on the two bikes. I'm on the 3rd set of pads on the SM, and have used sintered pads last two sets. Maybe that could have something to do with the wear on the rotors? I might go with organic pads when I replace these rotors.

Thanks,

Will
