Just wanted to pass on some information. I recently posted about how my rear rotor would make a loud ringing sound at speeds greater then 12 mph. I tried everything including re centering the caliper and every adjustment. I finally put the stock 2.0 tires back on replacing the 2.4's I had on there. The sound was gone after that. Apparently larger tires with the larger foot print were creating to much flex.
Another thing I noticied was that the rear rotor moves under weight. I weigh 200lbs and when I sit on the bike I can see the rotor move within the caliper. I had to adjust the caliber so that it would rub when off the bike but when on the bike the rotor was center in the caliper. Hope this helps others.
