Star nut problem

Hi, the star nut in my new fork did not go straight into the steering tube. How can I fix it?

Do you mean it has gone in fully, but it's at an angle?
If so, you could try screwing a bolt (that's long enough to protrude from the top of the steerer) into it then using a hammer to tap the bolt (sideways, not down further into the steere) until it's centred.

Yes it is inside but it's at an angle. I did try with the screwing bolt from the old headset cup but I manage to bend the bolt. I will try again with another bolt. Is it possible to remove it?

Depends how firmly wedged it is/how far down the steerer.
In the past, I've got lucky with wonky starnuts, and have managed to pull them back up the steerer, but if that doesn't work, it's normally a case of bashing it down the steerer until it pops out at the crown. If your steerer is internally butted, then this may not work either, and you'll be stuck with a useless starnut in you steerer.
At least you can then set one above it.

get a long thin screwdriver with a thin handle that will reach in through the steerer so that the handle of the screwdriver can sit against the top of the star nut. It will sit at an angle, tap it gently down whilst straightening the handle up. You might have to use a longer top cap bolt, but this will fix it easily, and if you do knock it too far down does as landslide said, just install a new one, using the same screwdriver

Thanks to both, I will get a new longer screwing bolt and screwdriver and try to fix it. Or else I will put another one on top of it. lets see.

how did you get on ??

have this problem with one of my bikes also !!

but just went for the new starnut option. can live with the extra weight

you can use a Ring-go-Star instead, much less bother

Or a Hope Head Doctor.

Can you use a hope head doctor on steel steerers?

Yes, of course.

or get the proper tool and do it correctly in the first place...

this is one of those jobs that requires patience while you wait to get the proper tool.

The proper tool is nice, but it isn't necessary, it is only a drift, and the right size screwdriver does the job perfectly.

I use a piece of alloy pipe about 100mm long 20mm wide when I fit star nuts, its wide enough to push the star nut into the steerer square as long as you get it started OK and soft enough not to damage the nut when hitting it with a mallet
