Will agree with Tim, that the o/p should check his brake pads. However, will also agree with David Craig and suggest the person also pull the tire, tube and rim strip and make sure there are no cracks in the rim with that wear. Had two Velocity rims crack internally, so am more paranoid about them
However, as that seems to be all the way around the rim, would think it's more an issue of the pads.
