hi guys, please i have a problem bothers me, i have a squeak when the forks of my bike are pressed, and also when it's rebound, my bike is rocky mountain vertex 30, i hope you to help me to fix this squeak. method, steps .. ect
thanks in advance

An what are the forks? without knowing what are fitted to your specific bike, not much help can be offered

The squeak may be from the seals sliding on the stanchions, in which products made to lube the stanchions may solve the problem easily. However if the squeak is originating within the fork, then it's necessary to know the specific fork model, or at least the type, ie, spring, oil or air suspension.

i bought the bike as it is, the forks fills by the wind " air suspension" , can you help how to know more about my forks in order to fix the squeak ?

thank you my friend for this advice,
the type of my forks is air suspension, that's all what i know about my forks. i'm still need your help, step by step.
i think the lubrication solution may fix the problem, what i want now is to give me the steps to lube the stanchions "how", and thank you so much .. waiting for you

Search "suspension fork stanchion lube" and you'll find links to products, and other discussions of the issue. Then you can take it from there depending on where you are.

i have the product of lubrication, i want to know only the way to apply it on the forks "type : air suspension".
when i search on google i find only the solution for the others forks types, not air suspension !

Unless the fork as had all the decals removed, all MTB forks on the market have their brand, and model prominently displayed, Does it have them?

From the picture, it's a Marzocchi fork, which would indicate it's from 2004-2009 going by Bikepedia, although each year of the Vertex 30 used a different fork model.

As it's a bomber chassis fork, unless you want to pull it a part (and that's not hard), just get some silicone spray, and spray the seals to see it that stops the squeak.

there are no signs or signals to know the type of forks, due to your experience in this field, i'll give you some pictures of my bike in order to know more about my forks maybe you are able to determinte it

i apologize, because you're tired of helping me, thank you so much

The 2004 model matches you spec & decals, see here 2004 Rocky Mountain Vertex 30 - BikePedia

The forks are the EXR Comp model, put this into Google, and you have lots of info, MTBR is very good researching older forks like this, sa in this thread, which includes links to the service manuals Marzocchi EXR Comp- Mtbr.com.

With Bombers (the EXR are one of a lot of versions of this), there isn't too much to go wrong on them, the seals will wear out in time (the same as all MTB forks) but the basic design is solid, and easy to user service.

exactly it looks like the forks which i own, so i think you're able to find the model of my forks, thank you very much
if i want to change the forks, what do you recommend? how much ?

You Take them apart from the bolts on the Bottom. down by the dropouts.

after opening the bolts at the bottom. What do i do?

Oil the dry places, replace seals

1st Id get the tech manual ,

If I were You, the fork (If its as above ) not the framebrand, they just bought forks from elsewhere
may be a rebuild kit for that fork

alternatively Buy a New fork. get the Manual with the Next one, maybe the rebuild kit for Future Overhauls

stuff is discontinued and abandoned by Makers all the time as the new stuff is released ..
