Carbon Fibre

Carbon bikes should be silent.. what sort of noise is it making? Creaking? When does it happen?

yeah, good old creaking carbon 🙂

Get someone at a shop -- preferably not where you bought it -- to isolate the noise coz it can be very tricky to pin-point. It could be coming from the front (bars, stem, forks) or the bottom bracket.....even the seatpost!!

Yep... I agree with 531Aussie. The sound is probably coming from components, not the frame. Also check your hubs (e.g., creaking Kysrium Elites).

I broke down my drive chain a few weeks ago and the next ride there was a creak out of the back end that was driving me insane. 3 hours of Chinese water torture!! I got back and stripped everything back down and couldn't find the culprit ... eventually found the little screw down nut on the tube valve was loose. So after an hour of poking about a quarter turn on the nut and it was fixed!!

I'll echo the other posters. It's unlikely to be the frame itself as opposed to a component someplace. Wheels, bottom bracket (especially after riding in the wet), stem, headset all worth going over.

Thanks for that.I have been out in the rain recently.I will give it to someone who knows more about carbon than me ( which is nothing ) ,and hopefully they can sort it out before i go pulling the whole bike apart.

Cheers

Every time I take the wheels off my Six13 (With Carbon Forks an dropouts) I get a creaking noise when I am out of the saddle...so I re-torque the Skewers and the noise dissapears immediately...this is a known issue with Mavic Skewers...maybe others too? But it's an easy thing to check....

Cheers then.

As 531Aussie pointed out in a roundabout sort of way ( 😉 ), if the noise is a creak (or most other noises for that matter), it's not coming directly from the frame -- carbon frames just doesn't do that. (Then again I could tell you a story about an vintage LOOK carbon frame whose metal lugs and inserts were about to delaminate themselves to bits...)

The only sound my carbon frame's ever made is a sloshing sound when there was some water trapped in one of the tubes (easily drained out the seat tube).

If you can let us know what sort of sound it is (creak? tick? twang? crunch? slosh? etc), and when it occurs (i.e. only when pedalling hard? only when out of the saddle? at a particular point in crank movement? only in some gears? etc.), it'll be a valuable indicator of what the problem might be, and where to start looking.

Unlike metal frames, which tend to amplify sounds (making it a pain in the [censored] to find exactly what it is) carbon tends to muffle things, making it easier to pinpoint the source.

Hey congrats Rek on the 1000 posts.Nice one.

It seems to be a tick noise when I'm pushing up a hill or in a harder gear.I'll make some notes on Australia Day ride and let you know.

Cheers, and safe riding.
