Anyone else come accross this? Seems to be something like a 7mm? Who the hell uses a 7mm allen bolts?

Now I need to find a shop that sells one :-(

Weird, just thought I would share.

Used to be fairly common on Italian stuff like 3ttt and old Cinelli. Even Campag C-Record cranks used a 7mm auto-extractor, with a left hand thread...

It's not all that uncommon on some brands of car too. Google and you'll find plenty.

frenchies or whatever it's called on holloway road sell 7mm allen keys, if that's any help.
and yea, i had a cinelli stem with 7mm bolt. also, i had a bunch of different cinelli stems, all the same model but some which were rounded off, so was gonna just swap the bolt over but i had a bout three different bolt diameters so couldn't swap them over - another weird one.

I think i have an old raleigh stem with a 7mm bolt, it could be a bolt from another stem though.

I had a 3ttt stem which came with the Raleigh.

Bought a 7mm key near Baker Street which was used once.

Don't need the key anymore.

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

For syntax highlighting, surround the code block with three backticks:

Just like Github, a blank line must precede a code block.
