Quill stem for threadless fork

I just bought a Viner Nemo frame with a steel 1" threadless fork off of Ebay. I have some old Campy parts to hang onto it and more to buy. I saw this quill stem that it say is for threadless forks. Is this a typo or will it work? Thanks.

Bikes: Crap. The box is not big enough...

the threads on a conventional fork are what holds the fork in place (well, the nut that threads onto the threads...). With a threadless fork, the clamp-on stem is what actually holds the fork in place. If you mix technologies in either direction, you will be unable to secure the fork to the frame.

That's what I thought, but I prefer the look of the quill stems. The bike's gonna a be an eccentric piece an I want all of the parts to be shiny and skinny;-)

Well, you could jig something up. You could use a clamp to hold the steerer in place, then use the theaded stem. You'd probably need to cut some threads into the steerer so that you could put a locknut on it so it looks good.

Kind of like how Sheldon Brown (pbuh) did but he used a threadless stem.

The clamp ain't bad, but where would you get one? I wonder if a quill stem would fit firmly inside the steel steering tube. I have an old Cinelli 1A that I'll try when the bike gets here.

This probably isn't going to work. There is a reason that things are designed the way they are. Like it or not threadless is a superior set up, quills work just fine but they are in no way better so why revert back to dated technology. There is no reason to have a janky set up like that chances are it won't fit anyway. You would be much better served looking for a lugged threadless stem.

Bikes: Many

Sheldon used a quill stem in a similar configuration on his multi-handlebar...

https://sheldonbrown.org/thorn/index.html

A threadless system with a clamp (Sheldon used a seat post clamp on the bike listed above) can accomodate a threaded stem.

I would only try it with an alloy, or preferably steel, steering tube...

From what I understand a threadless steerer is the same as a threaded steerer except that...



(drum roll please)



... it doesn't have threads.

Except for the fact that the whole point of threadless was to reduce weight, and alot of the time the wall on threadless tend to be thinner because they dont need any extra mass to make up for the cutting. Also just because it can be done doesn't mean it should be.

Look for something along the lines of this

Or.

Or keep an eye out for a threadless Cinelli Grammo. That is a good looking stem but I cant find a good picture

It might just work. Often steel threadless steerer tubes have the same thickness as threaded. Sometimes they are not. Take a measurement and see if it is the right size. If it is, then it will work.

I'd be careful threading the steerer tube if you want to put a locknut on it for aesthetics. Just thread it enough for the locknut to go on, but not all the way to the clamping area. It might be hard to find the right tool to thread the steerer. I have not checked all LBSs but I have heard that most only have the die to chase the threads or the one to extend the threads, not the one to start the threads. A frame builder might have the correct tool.

I agree with you, a good looking quill stem is much better looking than any threadless stem. I want to find a quill stem that has a pop top so that I can buy the bars I want. Right now I have one of those adapters to be able to use the threadless stem on one of my bikes. Just not the same. But, so far, the only ones I can find are welded and I hate those more than threadless.

I think the fork really goes with the frame and reduces the option of going with a threaded fork.
