    Default Ambrosio Nemesis Counterweight Is Loose

    E81A429B-42C2-4730-9EF5-2A05370B4B41.jpgHas anybody had to deal with this? Or can anybody without tires currently mounted take a look inside their rim and see how this thing is fastened? I could peel the tire off and look myself but I am only 130 miles into newly mounted Corsas and would rather not.
    Thanks.

    You could definitely use Mastik to hold it back down. I think I have an empty rim in the basement; will check for you.

    IMG_4382.jpgThis is my good rim. There is a rivet like fastener that was holding the counterweight against the rim and that has lifted on the bad rim.

    Pull that Massey Ferguson off and skip it across your favorite pond.

    My recollection is that they are fastened with a split nut like a chainwheel nut...It likely *IS* a chainwheel nut. To do it right you need to peel of the tire, tighten it down and re-glue.

    No glue required. Just needed to get Grandpa's screwdriver after it. Thanks.

    You should be ok. The guys who suggest to just glue it? Not so sure.

    Explain to me why a counterweight is where the valve is - shouldn’t it be opposite the valve? Or are they using a chunk of something to hold the rim joint together?

    I think it's sort of like an Italian pinky ring, no purpose but somehow indispensible

    I think the rim is sleeved at the joint opposite the valve hole. The counterweight plus the weight of the valve would balance the sleeve?

    Correct.

    Since it's a shallow rim you're likely to use an inner tube with a short-stem valve, hance it will have less mass to oppose the joint on the opposite side of the rim.
    That is the reason why people loved the Open SUP/Open Pro so much, their welded joint had (still has) less mass than usual resulting in a very balanced rim. Nobody likes wheels that when at speed feel like a broken food processor.
