Rattly Rim

Simonb said:

Funny one this: when I tap the rim I get a buzzy, rattly
sound from it -- but this only happens when the tyre on th
rim is fully inflated. If I remove tyre, tube, QR and
magnet, and hten tap the rim; I get nothing. I've checked
all the spoke nipples and the hub and everything is tight.

I've noticed the same thing occasionally. I think it still
could be something to do with the rim despite it not being
audible when tyre & stuff is removed. Maybe pressure from
the tyre exacerbates it?

Something funny with spokes? Loose eyelets? Loose rim joint
weld pin/piece? Certain Mavic rims (particularly Open Pro)
are known for sometiems having rattling bits loose inside.

If you have presta valves with a lock ring, check that it is
done up properly. If it is slightly loose, you can get it to
rattle against the rim.

First thing I checked. Thanks anyway.

Or remove it altogether and lose it down a crack. Many
people claim that this helps reduce punctures (though I must
admit, I've never really seen why)

Because it provides the valce stem with slightly more free
movement before it rips out of the tube.
