CCDB owners help! Loud noise

[funkyflea]

Hi,

I just got a ccdb and it sound very much compared to my Fox RC4. I found this video on youtube and mine sounds the same. Is this normal for the shock? I guess its the oil passing that makes the sound but this loud?

This is video of my bike without the spring attached.

Thanks!

Two thoughts:
1. It sounds like my mattress when I am getting down and getting funky.
2. Were you trying to kick start it? Its a bicycle, not a motorcycle.

Other than that, I am of no real help or contribution to this conversation.

that squishing sound doesnt sound too different from the two DB shocks ive had



i wonder if that person ever got his bike to start

[illnotsick]

Is he just gooch ramming the seat? Why not stand on the pedals?

didn't watch the video...


spring rubbing the shock body?

I think he actually took the seat off, and the noise we are hearing is not coming from the shock.
Those flowered shorts could very well be crotchless.

Sounds normal to me

Mine was doing this. Kind of like a honking noise. Check to see if the spring is rubbing on the black plastic cover over the shock body. When I bought a ti coil mine rubbed bad. It even rubbed with the Cane Creek stock spring. I ended up cutting the black piece off and solved the problem.

thats the only sound I get from mine,Ironicly ti spring makes diff sound from steel spring.were are my engineers to back this up

[IH8Rice]

it doesnt sound like its rubbing at all.

what the hell in **** ppl?!?

dude, you have air in your shock (where it isn't supposed to be). go have it's oil changed and properly bled.

[Wa-Aw]

Sounds perfectly normal to me. Some good damping action going on there!

[baca262]

knowing how ccdb works, no. there shouldn't be any cavitation (and therefore sound) at all, especially not at such low shaft speeds. there must be a bit of air in the damping chamber and this makes it go whoosh.

edit - btw there shouldn't be any whooshing sounds coming from any pressurized shock at low shaft speeds otherwise they weren't properly bled or air managed to blow by some seal (though this is VERY unlikely without total damping loss)

That is actually not good, there is air in the shock - assuming it's damper noise, I'm sure you wouldn't have posted a thread if it was the spring.

I have had CCDB's come from factory like that, however I have also had quiet ones (of the same year/model) which tells me the noise is not normal and it's just the result of an airy bleed.

If it bothers you, a service will probably sort it out, it's also worth checking the shaft seal/wiper area for leaks which could let air in - if there's any leaking present they should be replaced during service. Probably best sent to CC for this.
