Is your evidence that both sides were bulging equally the observation that the rim would strike both brake pads at the bulge? Striking both pads does not imply a symmetric bulge. A one-sided bulge will rub both brake pads as long as the bulge is big enough to take up the total pad clearance on both sides of the rim. The bulge pushing on the proximate brake pad will cause the opposite brake pad to be pulled against the other, non-bulging, side of the rim. I have a similarly worn-out and cracked rim that I should get around to fixing someday. It binds both brake pads, but only one side bulges, as measured on a truing stand. BTW, the bulge can only be measured with an inflated tire. Take off the tire, the bulge relaxes and the rim seems perfectly true. -- Mark -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
