Stem question from an idiot (apparently)(4 posts)

Stem question from an idiot (apparently)Jusme

I have a mid 80's Peugeot, and ordered a new quill stem for it. When it came, instead of having the little wedge it is just flat at the bottom with a bit of screw sticking out. I looked back at the catalog and this is how it's pictured (without the little wedge). How does this thing work?

Later I will have more difficult questions, like how do you put air in a tire. :^)
It works....Dave Hickey

The wedge is actually inside the stem. As you tighten the screw, the bottom of the stem expands.

With that type of wedge, just loosening the quill bolt will not loosen it like usually happens with the true wedge type.To loosen, so the stem can be removed or adjusted,one has to loosen the quill bolt enough that it is above the level of the sent and then hit the bolt to dislodge the wedge from the base of the stem.
Be sure the Quill diameter is 22 and not 22.2CarbonTi

French bikes have their own rules, after all, they are French...

Not a French bike enthusiast but bikes of that era had steerer tubes sized differently than the rest of the bike world so a 22.2 won't fit.
