Anyone ever experienced anything coming loose inside the sealed chamber of a CrossMax SX wheel? The wheels have only had a season and a half on them with not much abuse (I don't have those kind of killer abuse skills). Something is rattling around between the spokes.... all the spokes seem tight and nothing appears to be broken from the inside or outside. Since it's in the sealed part of the wheel, I don't think there is much I can do other than put up with the noise and keep an eye on it. Mavic is overseas, right.... again limiting my options on what I can do. Even took it to local shop just to get an "expert" opinion, same story.

Thanks in advance.

Are you running tubeless? Pull out your valve stem and rotate the wheel so the trapped rock falls out.

That's just the thing, it won't rotate from it's current position. It's like it's stuck in a chamber or between something...... and I don't think it's a rock.

It could be a piece of slag from when the eyelet was punched and threaded. You may have to remove the actual spoke and spoke retainer in order to remove the loose piece.

I have had several Mavic rims that have had the alignment sleeve come loose inside the rim cavity. This sleeve is used to hold the ends of the rim extrusion in alignment durring the welding process.

Couple fixes I have used:
run a little superglue at the first spoke hole from the seam, and set the wheel so the glue runs to the seam/sleeve (easier for non-tubeless rims)

The rim bed should have two small dimples near the seam (to hold the sleeve in place). A gently tap with a sharp punch/hammer will deepen the dimples and stop the sleeve from moving.

It's an aluminium block they glue inside the rim channel, at the welding point, as a reinforcement for the joint. I have seen several cases of that metal piece ungluing and coming free. A buddy of mine solved it by dropping some hot epoxy glue by the nearest nipple hole.
