Headset/star nut question(5 posts)

Headset/star nut questionShad
May 9, 2002 8:25 PM
The top cap screw on my CK headset pulled the star nut up to the top of the fork steer tube. I pushed it back in place with a star nut setter, but I'm wondering if this is common? Should I be replacing the star nut or doing something to make it sit more snugly in the fork steer tube? The headset isn't excessively loose right now, but it doesn't seem like I can tighen it any further without the star nut pulling back up. It makes me wonder if I actually have the headset adjusted tightly enough. The steer tube is Ti if that matters.

Thanks for your assistance and advice.

Makes me wonder if you used the correct diameter star nut or installed it in the correct orientaton?
Don't know, I didn't install it. How can I tell? nmShad

Whenever I've encountered this problem in the past, the cause was someone trying to tighten his headset without loosening the stem clamp. The only thing that top cap adjustment does is to set and hold the pre-load until you can clamp the stem down to hold everything in place.

If that isn't your problem, I'd guess it has to do with the titanium steer tube. Titanium is pretty hard and maybe the star nut isn't grabing the sides well enough. If that's the case, the "A" answer would be to contact the fork manufacturer and ask what they recommend. The "B" answer would be to try some kind of expander plug. Trying another star nut would rate a "C" at best, probably lower. If the first one pulled out, why wouldn't another do the same thing?
