Idiot stumped by rubbing sound

[Arjimlad]

Or ..
..... it sounded like a skeleton having a w**k in a biscuit tin.....

Sheer poetry, thank you for that ray of sunshine.

I had a funny crunchy sound on my commute home last night, every revolution a constant crackly noise, turned out it was the Snappy Reflector i wear round my ankle SHEESH

 

[Moodyman]

My bike has been ghostly quiet the last dozen rides. I still turn my head sideways when I hear odd sounds but it turns out to be worn bearings in a passing transit van or a wobbling flagpole in the wind.

When you're so used to having noises from the bike if kinda feels (or sounds) odd when it's silent.

Or wear earphones and turn the music volume up.
My mate did this with his car. He had a old Renault 19 that rattled so much it sounded like a skeleton having a w**k in a biscuit tin. I asked him about the noise. His reply was that when he was on his own he just turned the music up until he couldn't hear it anymore. Problem solved.

Friend of ours had a rattle in his car so he asked his wife to take to the garage

Garage could find nothing

As soon as he got in the following morning there was the rattle back again.

His wife returned the car 3 times, but they found nothing, but each time he drove it the rattle would return

So he eventually drove it into the garage himself where they diagnosed a metal tool box with spanners as the cause

Each time his wife had taken the car to the garage she had tidied it, taking out all the personal stuff including the tool kit

Hence no rattle when in the garage

Defo check clothing. try riding in just shorts and base layer shirt if possible ,

This is titillating.

but do us all a favour and just take the mudguard off, regardless of how much clearance you think there is!

 

[Ajax Bay]

I've ruled out the . . . mudguards (that rear guard has at least half an inch clearance all the way around and probably 3/4" where the bracket is).

How can you tell how much clearance there is, when you are sitting on it? Get your mum to sit on it and then check again.

"How often have I said to you that when you have eliminated the impossible, whatever remains, however improbable, must be the truth?"

You seem to have eliminated almost everything. Have you properly checked the chain? It seems unlikely, but ... I had a similar problem on a motorcycle. Regular shushing noise, unrelated to engine speed, varied with road speed but 3x (or 1/3, can't remember) the wheel rotation speed. In the end, it had logically to be the chain, and a new one cured it. Even a new chain might have a stiff link or something.

 

[Banjo]

Riding naked will cure it definitely. You wont hear anything over the noise of chattering teeth.

It's next (probably last) on the list, I was going to do it today but it was raining so I went to Waterstones and did some browsing instead.

 

[RichardB]

If that's not it, the only thing I could suggest is to ride the bike until it makes the noise, with someone running or riding alongside trying to identify the source. I once saw a car being driven about with a man's overalled legs sticking out of the open boot. It was a garage trying to trace a rattle for a customer, which only happened when the car was being driven. No need to go that far, perhaps.

Aw maaaaannnn, you can't leave us in suspense like this.

Spike Milligan was once phoned by Peter Sellers @ 03.00h one morning to help trace a squeak in the back of Seller's Roller. So a pyjamad Milligan was put in the boot of said Roller with a stick of chalk + torch and instructed to put a chalk mark wherever he thought the squeak was whilst Sellers drove around London. All was well, until a suspicious peeler pulled them up and opened the boot. Nuff said - !

 

[palinurus]

I was riding home today feeling very contented, no traffic around and I was aiming at small puddles so I could watch the droplets of water leaping from my front wheel being illuminated by my headlight, it was nice.

Then I realised the noise had gone away.

I'm sorry, it's really disappointing. I didn't intentionally do anything to make it go away.

I've lost all sense of purpose now.

 

[palinurus]

I feel nervous, like I should stop riding it until I can work out why it's gone silent.
