    Normal considering carbon wheels. Buddy of mine using 88 rims sounds exactly the same.
    Its like an echo or resonance to your rims

  2. Carbon wheels are loud. Some chains are louder than others.

    But this screams too much chain tension. 

    When people say the chain should have 1″ of up and down movement they don’t mean forceful. They mean 1/2″ of slack.

    Theres a few things that can make it like that.

    Chain tension, chain line, chain/cog wear….

    Imo its prob the chainline thats a little off, so what youre hearing is the cog engaging/disengaging with the chain instead of flowing over your cog smoothly.

    I liked the slowmo sound, could be part of a beat or a kind of like a transformer noise

    If chain breathes, likely just all the new parts pairing and resonating in the carbon echo chamber….chain lubed properly? Chainline? Idk

  5. That’s the sound of new components chattering! It’s normal, and a good break-in period will remedy it (for the most part) but you will always have a light and delightful chatter with the Izumi chain.

  6. Sounds smooth to me, new parts especially Izumi chains do make this kind of noise paired with new cog/chainring

    My Izumi V sounded like a motorcycle chain when it was new. Now that I think of it, all my Izumi chains have been loud when new.
