3ttt Stem Question...

[Mr Weirdo]

Hello

I have always used SR Stems, etc and the bolt that holds them to the headset/headset tube is easily accessible at the top and an Allen key can be used to remove it.

Now I have a 3ttt stem which has a cap and when you remove the cap you can see the head of a bolt? How do I untighten this bolt and with what tool size please? I can't make out whether it is an Allen key fitting or not?

Thank you for your help.
Please ignore hole in sock...I do

Should be an Allen key, it’s 6mm for most I think.

Thank you so I need to buy one of those long shaft type Allen tools and the not the short L shaped ones.

My vision is a bit dodgy so I could not see the head of the bolt as well as I would like.

Thanks again.

If you’ve got an Allen key socket set I ground the socket bit down until it fit in the hole. Then you’ve got some leverage

Use an L shaped tool and hook the ring end of an adjustable spanner though it - giving you get the leverage to undo.

Thank you for the useful info!

I prefer a socket and extension on the short end.
