I've been having issues with metal fragments flaking off my rims and embedding themselves in my brake pads. This has been occurring since the bike was new (bought it last summer). I've never had this issue in my 33 years of riding bicycles. You can clearly see that the rim surface does not have a smooth finish. I'm guessing it's a manufacturer defect because I can't see how else this could happen. Has anyone else had this issue? The bike is a Specialized Crosstrail with 700c alloy double-wall CNC sidewalls pin joint 32h (whatever that means). Here is an example of one of the pads. All four look like this. The gouges are from when I previously removed fragments.
