Strange sound from cluster when freewheeling

[Shaunpr]

Hi, when I am on a fast down hill and my racing bike is maxed in terms of speed and I freewheel there is a strange noise emanating from the cluster, then if I continue to pedal then the noise dies. This only happens at higher speeds. Could the bearings be finished? Ho do I fix this?

What free hub do you have? Is this Mavic by any chance.

Well at least I know what your noise sounds like now.

That is a regular issue with Mavic Freehub. Caused by the plastic / ceramic insert A small amount of oils or grease will stop the noise for a while but eventually you will have to replace

Not what I was hoping to hear. Thanks none the less.

Don't ride it like this, get it fixed. I wrecked my frame with a mavic hub failure, turned out to be expensive.

Thanks for this

Recommendation: dont use Mavic hubs. You can do better for less money: Shimano, Hope, DT, etc

Listen to this guy. He's clearly had experience.

I've had the same issue. Mavic hubs are easy enough to open up and oil the offending part. But, like others have said, it will eventually wear out.

Thanks Jacquers

 

No problem.

 

I think I used Wynflon (that has PTFE / Teflon in it) that I got from Midas, but any any oil should work.
