    Worn carbon brake track?

    Hi all, I just bought these Chinese carbon wheels used and am concerned that the rims may be worn out. A bike mechanic friend of mine (6 years, ex cat 2 roadie) says that they are good to go but I am still concerned. Call it paranoia, but I would appreciate a second opinion. Let me know if different pictures are necessary. Thanks in advance for your input.

    I don't see a brake track on those rims. They look like they are disc specific. If they are designed for disc brakes without a rim brake track they are no good for using with rim brakes.

    I would contact the seller/mfg. If the are Ebay wheels you are probably out of luck but if they are were purchased from a reputable Chinese company they may back up their wheel. I put over 2000 miles on my new Chinese wheels in 2018 and my tracks aren't shiney like that. What are you using for brake pads? Mine came with 2 sets from the mfg (Far Sports).

    ??? Are we looking at the same photos? Looks like there is a small amount of wear.

    So the rims are slightly worn but still have a significant amount of miles left in them?

    The marks look like they were made from grit embedded in the brake pads. I would purchase and install new carbon-specific pads and ride them. I inspect and clean my carbon wheels and brake pads every couple of rides just to monitor any abnormal wear.

    Also, never run aluminum wheels using these carbon-specific pads. If you want to alternate between carbon and aluminum wheels make sure you change your brake pads too.

    There's a different photo showing now than there was before. Strange.

    I would check to see if the brake surface is concave. The center of the brake surface will typically wear more then the edges.
