Hey, I need some help to try and id a weird sound my Neutron Ultra's rear hub has started making while coasting. As you can listen in the video, it only happens when the cassette is at a certain position.

I disassembled it, regreased the pawls and check the little spring that holds them in place and everything looks ok.

Any idea what could be the problem? Do I need a new freehub body?

Definitely does not sound good.

Take it off again and check the bearings inside the freehub.

Until you find out for sure what is causing it I would not ride it. I had a freehub bearing failure once, and it was ride ending experience.

It sounds like ring spring went off of the its place in freehub, or one of pawls is not on its place. Had while ago similar noise in Shamals

Well looks like it's what bikerjulio said, the bearings inside the freehub. One is super gritty, the other one is ok. Nothing wrong with the pawls or ring spring that I can see.

Do you think it's safe to ride them until I get a new freehub or manage to change the bearings?

I just checked Strava and they lasted 16K km on dry weather.

Changing the bearings is not an official Campy procedure, but it can be done. You'd have to google it.

Officially, it's a new freehub needed.

All depends on your level of mechanical aptitude with these things.

Riding with a destroyed freehub bearing is not a problem at all, but, the more power you put to the rear wheel, the more drag you will encounter. You will get home for sure, but you won't ride again with that shot bearing, believe me. I went through 2 freehub bearings, and it was night and day when back on a good working one! If shot, replace the whole freehub.

This is not damaged bearing sound.

Hi There.

Exact same problem occurred to me yesterday towards the end of my cycle. Loud noise when coasting only. Neutron Ultra rear wheel. I had blamed a banana skin I somehow managed to let slip through the back wheel a few minutes earlier. I haven't yet ruled that out.. I will take my hub apart later and update you.

Unlike the poster my wheels have only done 2000km. The weather was dry. I managed to make it home simply by engaging the cassette for the remainder of the journey.

Question for the original poster. Did you manage to get rid of the noise and if so how?

Cheers Ray

My recollection is that a bearing came apart within the freehub "locking" it to the spindle. ie nothing would move.

So, yes it was most definitely a problem.

I'm waiting for a replacement freehub to arrive, not new but it's supposed to have just 300 km. The procedure to replace the bearings is a bit of a pain, at least to me, so I did not try.

Ray you can try disassembling it and having a look, I'm not too mechanically inclined and it's a very easy job, just be careful with the pawls when fitting it back. With just 2000km I don't think it's the bearings.
