Framebuilders - Steer extension

Hello,

I need a really tall handel bar extension. I thought of the Razor, but that is for 1 1/8ths and I have a 1" threaded

any adapters? or or any other thoughts? i have seen some for recumbents, but i am also doing a budget build.

15cm of useful extension which is "really tall" for me, maybe not so much for you.

I didn't know about the extension that eric c posted. Your other alternative is that Nitto makes some really tall quill stems. You may also be able to find a tall quill adapter.

well, dose anybody know what type of threads a 1" uses? is there any type of plumbing 1" to 1 1/8th adapter?

the threads on a threaded steerer can't support a stem, you'll rip them off.

maybe this is easier......

i built a upside down bike. and i need a tall extension. i thought to use a razor bar/stem deal. but my fork is 1" and the razor inside is threaded for 1/8ths. i thought some type of plumbing or something to adapt it. but not sure on the threads.

and is there a different forum for funky builds?

sounds interesting. Never heard of an upside-down bike. Threads on a 1" steerer are 24 tpi. Wouldn't be hard to cut something on a lathe. I can't imagine anyone making an adapter. You are going to have to make something, perhaps using old headset parts.

There is a funky build forum called alt bike culture (http://www.bikeforums.net/forumdisplay.php?225-Alt-Bike-Culture)

if you posted pictures or even a bad drawing of what you want to do it will make things easier for us or for the people in alt-bike-culture

174567This is what I think he's trying to do.
If it is I want no part of it.

if you want no part, why did you post?

my question is more about threads, and such.... the application is not relevant.

thanks for the help others.

thanks for the help others.No your question was about "really tall" handle bar extensions, with no quantification of what that meant to you.
Unterhausen and I both provided you with options, based on our assumptions about what you wanted, you then provided some more incomplete clarification of what you were attempting and I "painted" what I thought you meant and it must have been close since you didn't provide an alternative "paint" project.
That all said the application is completely relevant, because I know how I'd get where I think you want to go(if my paint diagram is in fact what you are atttempting), but I'm not willing to provide guidance in what I feel is folly.

.of course it's relevant. I can see applications where you could use the threads on a threaded steerer. But I wouldn't attach a really long unsupported extension to the threads of a threaded steerer because it will break off. I've seen way too many broken steerers to even think about it. That's why they used quill stems with threaded steerers, with very few exceptions that also did not involve long extensions.
