    Nope, never seen anything like that.

    How much time/mileage on that hub? Was it a stock wheel? Custom build or rebuild? Recently worked on?

    What year hub? Did the crack go through the hub, or only just the plastic shell? Least I thought the plastic outer layer was just a non load bearing cover...

    This is the first iteration of the Neutron with an alloy hub. I have them.

    The current "Ultra" has a different shell and flange setup. I have them too.

    Not sure the age but could be up to 15 years?

    Fatigue?

    There's sometimes a buggy.
    How many drivers does a buggy have?
    One.
    So let's just say I'm drivin' this buggy...
    and if you fix your attitude you can ride along with me.

    I have a set of Eurus also think it has the same hub, does help on confidence level!

    I have an email into Campy I will post what they say

    Had an issue a couple of years ago w a Velocity rim potato chipping on me got hurt pretty bad, there is a post on this site where the President of co got involved, he asked the rider in a scolding fashion why he did not contact Velocity 1st instead of complaining on RBR, he was really asking if anybody had the same problem like I did, so I contacted them they sent me a questionnare 1 Were the wheels custom built 2. were they machine built and something else, once they found out they were custom built they never even Replied back!
    F Velocity!

    They looked like my ca. 2006 Zonda set I bought forever ago and retired.

    Naw, After 10 years of faithful service the rear was cold-set off true and nothing could true them. Damn G3 spoking.

    Plastic shell? You can see the axle in the picture. Traditional hubs have a flange that is drilled for the spokes, but these hubs use direct pull spokes that connect to the hub shell (no flange). In a traditional hub, the spoke forces are on the flange but in this design the forces are in the hub shell. When there is high stress or a manufacturing failure (e.g. grain lines in the metal) this will be the failure mode.

    Good call, so you would tend to believe this is common problem with their hubs?

    I've been using Campy equipment for a long time, and active in the forums for a long time also, and yours is the first ever case I've come across like this.

    So no, it's far from being a common problem.

    Aluminium fatigue, probably. These are rather old wheels.
    I have two sets with the same hubs, a 2003 Eurus and a ~2005 Nucleon.

    Cold set: You mean galvanic corrosion "welding" two different metals together?
    They do anything just to win a salami in ridiculous races. I take my gear out of the car and put my bike together. Tourists and locals are watching from sidewalk cafes. Non-racers. The emptiness of those lives shocks me. It was the illest of times, it was the dopest of times. And we looked damn good. Actually the autobus broke down somewhere on the Mortirolo.

    I think he means work-hardened; as I understand it, it's when the crystalline (?) structure of the metal becomes distorted due to force(s) on the metal--e.g., the bending of a coat hanger; the force of bending compresses the structure on one side, and this cannot be uncompressed through "re-bending," so the coat hanger will never be like it was before.

    yeah, that makes sense!

    I will not comment on our Reality star leader, but this cabinet makes no sense!

    Cold set in common usage means "bent without heat." So you can cold set a steel frame to widen the rear triangle. Cold set aluminum is usually a dangerous situation because when you bend it, you damage it (unlike steel). A cold set aluminum rim would be out of round or out of true when you removed the spokes. To build such a rim into a round and true wheel you might see significant variations in spoke tension.

    Remember back in the day you could bend steel rear triangle to accommodate 6,7 and 8 spds. People used to use a 2"x4" if they didn't have the park or Campy tool! I had a aluminum boat that would not fit in my garage, I took it apart and took the aluminum I-Beams it to a trailer builder and he warned me that it may break, but would do it while they were rebending, he went on to day I would be alright after that, if it made it thru the rebending
