• How so? He doesn't seem to be dead set against Chinese carbon, I seem to recall he had a pic of a cross-section of an enve rim with voids in it?

  • and who says voids is a bad thing? whatever he is cutting up and showing will always look 'omg big brands are saving money by putting less carbon' etc. Who knows whats the best practice? I'd rather trust enve than some dude (he might as well have a PHD) in a garage for expertise.

  • Well the wiki appears to suggest that:

    Because a void is a non-uniformity in a composite material, it can affect the mechanical properties and lifespan of the composite.[1] Voids can act as a crack nucleation site as well as allow moisture to penetrate the composite and contribute to anisotropy of the composite .[2] This is an issue because crack formation and propagation can create unpredictable behavior in the laminate...a 1%-3% increase in void content can reduce the mechanical properties of the composite by up to 20%

    But I'm no expert...

  • This is brand trust at it's finest.

    If voids are meant to be there, why are they not uniform around the rim? From a mechanical point of view, a void on one side of a rim compared to the other side would make it weaker and more flexible, thus creating an imbalance, unless Enve designed this in due to assymetric wheelbuilds (which they most certainly didn't) then it's a QC issue.

    And the "some guy in a garage" point is null as well

    Raoul has also been involved with composite materials for over 25 years. He has been employed by Boeing Aerospace, Defence and the Australian Institute of Sport. He has extensive experience in quality control of composites, manufacturing and design. Raoul has designed and built many composite items, including items used in the Olympic games, the Malvern Star range of carbon bicycles which won an Australian Design Mark and the groundbreaking BC composites Tammar mountain bike enduro rim. He has worked with national, Olympic and professional athletes in a technology and equipment advisor role and is passionate about sports performance.

    So he's basically one of them.
