Freewheel noise

[fenners81]

hi
I've just bought a new bike and seem to be having no end of issues. Most recent is after about 150 miles there is a rubbing sound when rear wheel is in freewheel. Sound isn't there if pedalling.its only a slight noise but sounds the same as when brake pads are catching the rim very slightly. The tyre isn't catching anywhere and it sounds like it's coming from the free hub. Should I ignore this or get it seen to?

Pop it in for a quick check if you cant see the reason.
a free hub shouldn't rub..they do losen off and get noisier..some are sealed and some can be cleaned out and re lubed..
so all depends on what hub you have..
Do you know or can you take a pic?

Don't mind having a go. Where's the lock ring?

That's probably the sound of the freewheel - freewheeling.

hanks for that! No it's a rubbing sound, not the ticking of the freewheeling

Its at the end of the last cog on the cassette ..
This tool fits in the end in the lock ring /http://www.wiggle.co.uk/park-tool-fr5-cassette-lockring-remover/

Does the sound cause any friction? ie - does it slow you down? If not, don't worry about it.

I don't think it caused friction but I'm worried it might get worse.

Well don't. If it does get worse, then get it investigated. Meanwhile, just ride it....

Perhaps not a rubbing sound but my Fulcrums developed a low squeek and it turned out to be the rubber seal on the non drive side of the hub. Just a small squirt of oil onto the rubber seal sorted it instantly.
Probably not your problem fenners but for the sake of a 5 second look....

Ok, so I sprayed some 3in1 into the side of the hub and the noise has got worse! Any ideas?

It might be perfectly normal. There is a lot going on in a freehub. Two rows of small bearings, and the ratchet mechanism. Having said that, the bearings are not worked hard, as they only rotate when they are not under any load (when freewheeling). What make is the hub? Is it an expensive bike? I'd expect the bearings to be a bit noisier on cheaper hubs.

Probably not a wise move unless you are out in the middle of nowhere on a world tour, and trying to revitalise a knackered, slipping freehub.

The freehub is probably supposed to have grease rather than oil, so you've just diluted a fairly thick lubricant with a thin runny one, hence the increase in bearing noise.
