Another cinelli stem problem

I've searched and found similar problems, but nothing describing exactly the problem i'm having.

I have a Cinelli 1a, with expander bolt, and cant bloody get it tight enough. I've tried it with a 3 different frames, so i think that rules out an issue with the fork steerer tube.

Basically, I can get the expander bolt to engage fine, but it tightens up impossibly within a few turns, and the stem still turns easily within the steerer. I've even tried levering an allen key (managed to bend the allen key) in an attempt to get enough torque to tighten it. Still no help. I've taken out the expander wedge, cleaned the inside of the stem, regreased and checked the bolt thread, nothing has helped.

any suggestions?

are you running out of thread on the bolt before expander has done enough expanding?

Formatting Help

Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.

Tips:

Create headers by underlining text with ==== or ----

To *italicise* text put one asterisk each side of the word

To **bold** text put two asterisks each side of the word

Embed images by entering:
![](https://www.google.co.uk/images/srpr/logo4w.png)
That's the hard one: exclamation, square brackets and then the URL to the image in brackets.

* Create lists by starting lines with asterisks

1. Create numbered lists by starting lines with a number and a dot
