So I purchased a new set of CL50 carbon wheels exactly a year ago. LOVE Them! Just noticed the other day while cleaning that the wheels have some discoloration and it is not around the brake track (Rim Brakes). Has anyone noticed or had similar issues. The wheels seem solid and fine other than the discoloration. I emailed Specialized and Roval but have not heard back yet. I read about someone with HUNT Carbon wheels had something similar and they were told it was because of the process and resin used in making them. Anyone have any thoughts?
