Hi,
I want to replace the handle bar stem on my Gt arrowhead.

Can anyone tell me whether it a 1" or 1 1/8" stem and do I need a threadless or threaded type?

Cheers

If it's after 1996ish, then it'll almost certainly be 1,1/8" and threadless. :)

Forgive my noobishness but what is a "quill fitting"?

A quill stem:

And a ahead/threadless stem:

The quill stem relies on a wedge or 'quill' to tighten it in place. The fork steerer is threaded, and is usually cut flush with the top of the headset.
An ahead/threadless stem clamps to the fork steerer, usually using pinch bolts. The fork steerer is unthreaded, and extends up past the top of the headset to allow the stem to clamp to it.

You can only use a quill stem with a threaded headset, and you can only use an ahead stem with a threadless one :)

If you show me a picture of your bike and the forks you're using, I'll be able to tell you which headset/stem you'll need.

Yes. But make sure you get the right size!

Looking at your picture, I'd say you need a 1,1/8" or 25.4 one :)
