I have had these rims for a few years now but I might ride a couple hundred miles a year at best. The rear rim remained black while the front rim has turned brown. I'm guessing they're anodized, but the process was not done correctly on the front rim. So now, I have to disassemble the rim, replace and respoke and true a new rim. I'm sure you all know what a pain or cost that can be. Pro Wheel offered to give me a %20 discount if I wanted to pay for the shipping. Not good customer service IMO. Excels next time.
