play in headset/fork
 

I just installed a new threadless headset and the fork is a tiny bit loose.
any suggestions?
is it possible I put the star nut too far down the tube?

Just need to loosen your stem bolts and tighten the top cap screw down a little until you just lose that play, retighten stem bolts, good to go.

yea, I tried tightening it pretty good, will try again

Did you loosen the stem's clamp bolts first? If you didn't, tightening the top cap bolt will have no effect.

yup

I have the same issue and this worked. Thanks guys. This forum actually contains useful information!

OK, next idea: Is there at least a small gap (2 -3 mm) between the top of the stem (or any spacers above the stem) and the top of the steerer tube. The steerer has to be a couple of mm below the top of the stem/spacers. If the steerer is flush, tightening the top cap will just press on the steerer tube and no adjustment will be possible.

This is my guess, as well.

I think it's flush, so I'll try that, thanks folks

If it's only flush, add 2-3mm spacer(s). Flush won't work.

spacer added, play gone.
thanks for the suggestions.

Just asking ok? Did u check the fork Crown Race? If that thing is lose or even better is not in place correctly the headset will be lose. what I think is that maybe the crown race is not in place. Actually it is Pressed or basically hammer it onto the fork crown, did u use a metal tube or something to set the crown race in place?

thanks.
