Headset Movement

[George.E]

Hey

I posted before about my headset moving when i tightened it, I couldn't solve the problem so I thought it was time for a new headset.

I bought a FSA pig pro headset.

I have a Try-All stem

Echo Lite forks

And Echo Lite frame

I fitted my new headset and went on nicely, my star nut seems to be in tight on the forks.

I tighten the starnut bolt to the right tension to stop the movement then tighten my stem bolts.

It stays fine for about 1 min then just goes loose again.

Does anyone no what I might be doing wrong please?

Thanks.

Is it the headset moving where its loose or are the headset cups moving in the frame?

It's possible you've flared your headtube...

Did you use a headset press? or just hammer the cups in? Check if the cups are loose in the frame, if not, I don't know what it could be

did you fit the new crown race?

Got the crown race on the forks?

Star nut could need pushing down the steerer a tiny bit more.

Bearings in the right way around? All clean and greased up?

Can't think of much else...

I had a problem like this when I changed frame, basically the headtube was slightly shorter, so the forks come up inside the stem slightly more, which meant the top cap rubbed against the top of the forks when done up. It would be fine and then I'd ride it and it would get worse over a period of about a minute or 2.

Just check how close your top cap is to your forks, if its too close put another ahead spacer under or on top of your stem, or knock the star nut down a bit.

Sorry it's not the cups moving in the frame there fine, it's like the top race cap moves, like there's movement in the forks.

Crown race is on, I might need the star nut nocking down.

I have spacers on and the top cap is well away from catching the fork steerer

What forks do you have and how old are they, if they're forks with a bonded steerer then the steerer could have come loose?

Echo lites, an naa the steerer is fine, it's when you rock the bike back an forth it feels loose.

Right, tighten up your starnut and compression etc. then look in the slit on the stem (what makes it clamp onto the forks) and see how high the forks are, if they're to the top of the stem then you need to add a spcer underneath or cut your steerer down.

I said there is plenty of room between the fork steerer and the top cap .

Think I had something like this happen before, happened on an FSA pig, I took the off the stem which leaves the little ring which has a spilt and a taper that slips down between the fork steerer and the bearings, I put a spacer/s on and an old stem on that cleared the top of the steerer and then hammered the top of the old stem (you can put a bit of wood on top if you don't want to damage it) to push the tapered spilt ring down a bit more (you should be able to do it with the front wheel in to avoid your fork drop outs taking the strain when you hammer it down), then I took it off the old stem without disturbing the spilt ring and I assembled the stem/spacers as normal with the stem I wanted to use and preloaded the star nut as normal, think for me it was because the tension given by adjusting the star cap nut alone did not have enough force to seat the taper spilt ring down enough, but give it a go it worked for me

[japslap]

Thanks guys.
