Quill To Threadless Stem Adapter

[modernfuturist]

I'm considering going with a quill to threadless adapter on my new build, paired with a Velo Orange tall stack quill stem.

I remember finding some very good looking examples of bikes with threadless to quill stem adapters that looked relatively normal, but the links are eluding me at the moment.

What I'm trying to avoid is this goose neck type look here:

Is it just a matter of using the Nitto or Profile quill stem adapter?

Does anyone have any experience or pictures of other good looking threadless to quill stem adaptered bikes?

I assume you're going from 1" quill to 1 1/8" stem. Here's the Profile. If you chamfer a spacer to fit the short taper, it will provide a more seamless transition down to the top nut. The flatter the top nut the better. A Shimano 105 hex top nut has a flat surface on top that's just about 1 1/8" diameter, so the shim will fit the top of it pretty well. A Stronglight on the other hand, has almost no flat surface on top. You can use a different brand of top nut than the headset, in general.

this model of this part is super hard to find on the net in the US. I got one from these guys and it took about 3 days...faster than most US vendors.

this is the only one i have ever seen where the transition is completely smooth from headset to stem. they make two models. one that fits into one inch headtube and the other that fits into 1.125 headtubes. your 1 inch steerer stem goes on over their spacers. their spacers are used to adjust how high the extension rises out of the headtube. if you have a 1.125 threadless stem you can use a normal 1 to 1.125 shim between their spacers and your stem steerer clamp.

the one i bought may be available for sale in the next few days. not because it did not work as intended, but i may go to a very tall quill instead.

Shoot me a PM with your email address and I'll send you some photos of my Serotta. Uses the Profile threadless converter that Oliver posted. It'll at least give you some perspective of what it looks like on the bike.

I think it looks great and works well. But that's just my two cents.

Sounds like the OP wants to go from threadless to quill, so he can use a quill stem on a threadless steerer, not the other way around.


I've never heard of such a device, but I suppose it is possible, however unlikely.

Should have clarified, but this is not what I want.

I would like to go from 1in threaded to 1 1/8th threadless.

So you want to use this stem?

If by "goose neck" you mean avoiding the skinny bit between the top of the headset and the stem, I suppose you could just take the 1 1/8" Profile adapter and substitute a longer quill bolt, which should make it long enough to put on top of the Velo stem. Then you can get them low enough that the headset lockring (which is about 1.25") will nearly but up against the bottom of the Velo stem, which is also about 1.25" in outer diameter.

Is that right?

one inch threaded fork
one inch bbb extender
1.125 threadless stem - with 1 inch to 1.125 shim installed

would be even a bit smoother with old world 1 inch threadless stem.


shimmed stem slides over bbb-provided spacers.

You need to open up permissions to that picasa folder for us to be able to view it.

I know it's not what the OP wants, but such a device does exist:

Draw your own conclusions on the usefulness of such a device...

Still can't see it. The above is what happens when you drop the link into the Image display function.

I can see other folders. Brooks, Cronos, Tiggy tiggy. If it is in one of those folders, let me know which one and I'll post it.

That's pretty nice looking - I see how the 1 1/8" shaft sits right on top of the headset instead of tapering like the one MF pictured. Probably better looking than the effect of going from the headset nut to the Velo stem.

[modernfuturist]

Agreed, looks pretty slick. I think a combination of the BBB stem extender and a Velo Orange Tall Stack threadless stem, and maybe the correct headset top nut, and I should have a pretty seamless looking cockpit. Planning to keep it all silver, so now I have to find a nice 31.8 silver bar.

[Kontact]

Do you plan to have the Velo stem down against the headset, or start it a few CMs up?


Please post a pic when you get it together.

Why are you doing this, out of curiosity? What can this achieve that a quill stem can't?

[eddief]

It is not the shaft sitting on top of the headset. It has a normal quill diameter and that quill has moveable/removeable spacers slid on top of it. those spacers add to the diameter to make it the size of 1 inch threadless stem. you either put a 1 inch threadless stem over the spacers or a 1.125 threadless stem with a shim over the spacers. so it is actually the spacers sitting on top of the headset.

The spacers serve two purposes. increase the diameter of the unit and allow for the up an down adjustment of the quill.

Removable faceplate? I know I can't find any reasonably priced 3T, Deda or Modolo swinging face stems anymore.

Nor are there any 31.8 quills, but there are plenty of 26.0 bars.


It's too bad someone doesn't make a reliable fork steerer converter. But maybe it wouldn't be that hard?

[modernfuturist]

Just exploring which options I have out there.

I'd love to run a Nitto Dynamic II, but finding one has been tough.

Not really interested in running a Technomic with the quill raised all the way up (already have that on my touring bike).

Plus I dig how the VO tall stack quill stem looks, and I think it looks more slick than running spacers/tall quill stem.

Removeable faceplate and 31.8 bars are also advantages, if only ever so slightly.

[modernfuturist]

I saw that and was interested in a 90mm 90degree stem, but they only have the 75 degree in the 90mm I'm looking at (which isn't much of a difference with the Technomics or Pearls).

[brockd15]

That BBB adapter looks great...I didn't know it existed. Much better than the quill to threadless adapters I've used before.
