where to buy shorter quill stem? or conversion?
 

So my road bike still has a quill stem, and i think i need a little bit of a shorter stem as the reach is a little far for me. I look on performance bike and nashbar but cannot find a quill stem. At least i think thats the right name!

Or should i forget the quill stem and get a conversion?

What is the difference? Any benefits to this?

I dont want to add any more weight to my bike. I have a de rosa nuovo classico, so any addition would have to be a little bit more performance oriented.

What's your current stem length?
Here's a 90mm

Here's a 70. But you may need to have an awfully large frame or want an awfully high stem:

Plenty more around

I've put the conversion thingies on both my 1" threaded steerer bikes. The advantage is that then I can use commonly available stems from my LBS, swapping them around until I find one I like. Yet, they retain the height adjustment that's lost on threadless steerers.

I even use the Profile Design ones you pictured. They work just fine.

If you prefer to look of a quill stem and want to stick with it, Velo Orange has them, as does Rivendell.
