|Fondriest Fork Noise||yashcha|
Aug 18, 2003 7:52 PM
|Hello, I have had my fondriest MDC model for about a year now and now when I brake hard using the front brake, the headset area has developed a slight creak/clicking noise. I believe this might be the headset bearings moving around in the cups, but it could be something else. Anybody else have this problem? The fork is all carbon fiber, the headset has been cleaned and regreased and everything is tightened to torque. Is this a normal noise when braking hard? Thank you guys in advance.|

|If your headset is adjusted snugly then I doubt it's the bearings shifting, you would feel the slack causing the front end to "rock" to & fro. It's more likely the interface between any spacers & the fork column, or possibly the stem & fork interface.
I fixed an annoying creak from the front end of my De Rosa's all carbon fork by removing spacer & stem, regreasing ALL parts lightly & REBUILDING. Silence at last. Try one area at a time & eventually you will find the culprit, good luck!

|Hi, thank you for taking the time. I was wondering if you had greased the inside of the stem where it attaches to the steerer tube? Thank you!|

|If you have the Fondriest headset, it has sealed cartridge bearings. They don't appear to be "regreaseable". Are you sure that you have the top cap tightened sufficiently (before tightening the stem)? I would loosen the stem. retighten the top cap until there is a slight binding of the fork movement, then back the top screw just enough to relieve the binding.
Clicking noises during hard braking are not normal, but it could be other things, like the stem or even brake levers.

|Hello thank you for replying! I think the headset is indeed tight enough, I have been using a torque wrench as to not overtighten, but I will have the headset checked today.|

|Off the bike, lock the front brake and rock the bike back and forth. If the headset has play, you will notice it and this is your problem.|

|I too had the same issue with my P4 Carbon. It ended up being a case of too many spacers and not tighetening the headset enough.
I was trying to be gentle as my compressor cap is carbon and I didn't want to crack it by overtightening. If you hold your front brake and rock the bike hard back and forth, you'll see the play in the spacers. If this is the case, it's too loose or you just have too many spacers stacked there.
If you absolutely cannot lower your stem (due to neck or back pain, handling issues, etc.), try a stem that is 'swapable' with it's mounting.

|Hi Maurizio, thank you for your reply. i finally broke down and took it to an experienced bike shop, but I too thought that it might be the carbon spacers rubbing against eachother. I have about 1 inch of spacers right now and two spacers in that space. I also greased up the interface between the spacers. maybe I just need one large spacer instead of two small ones. Is that about how much you have? Thank you for your time.|| |
