I sent this pic, and a couple others, to one of my guy bike pals. He said it looks like the start of failure of the rim where the seam is. My bike is a Giant OCR1 wsd. I think I had read on here before from other owners that the wheel set was a negative about the bike. It reads "Xero lite" on the side. I pulled out my owner's manual, and it's one year on parts, but life ownership on the frame. Been well past warranty. Crud. Anyone else, just chime in please. Thx.
