    Mag 30 dh rim problem

    I recently got a bike with mag 30 rims, and when I pump the tires up 60 psi, something comes loose and slides around the rim, but when I take some air out it stops. I have no idea what it is. Ive taken the tire off heaps of times, and the sound stops, but starts again when I get to around 60 psi. The sound is clearly in the rim. Does anyone know what the noise could be? The only thing I can think of is something is lodged in the rim, and when the tube pushes the rim walls out the thing wedged in slides around

    Why are you putting 60 psi into a DH tire?





    You are hearing the sleeve on the inside of the rim where the 2 sides come together.

    Shouldn't be anything to worry about.
    I crashed hard enough on my Tallboy to break my leg,

    I ride to school so I put maxxis hook worm tyres on it, so that's why I pump it up
