Threadless to Threaded Conversion?
 

Hey guys and gals... Just a quick question. Is it possible/practical to convert a bike that accepts a threadless fork to accept a threaded fork?... I'm wondering because there are plenty of cheap frames out there that I really like except that most take a threadless type fork ( I prefer threaded ). Thanks for any help

Buy a new headset (and a threaded fork and stem).
And voila.

Only if it's 1" threadless.

Yes. Forgot that.

if the frame is a 1 1/8 good luck finding a threaded fork that will fit it....other than that, what hyper said

edit: damn i'm too slow

didn't tandems use 1 1/8" threaded?

I thought some MTBs did back in some day.

You can put this on your bike.

Googling for a good while didn't turn up a lot. Check out Harris Cyclery/ask Sheldon Brown if anything.

um...can't 'member where, but i've seen a 1&1/8 to 1inch headtube adapter. get that and a new fork...tah dah.

Frames don't care if the headset is threaded or threadless, that's just a concern for the fork and stem.

I doubt I'd ever do it, but is there good threaded fork that would go with a steamroller; that is, maintain the same geometry?

Uh, just get your threadless fork threaded at a reputable LBS. Pick up a headset and a stem, and you're in business (albeit less stiff).

this wont work with an aluminum steerer though right?

all I was trying to say is that it would be a lot more difficult to find a 1 1/8 threaded fork for a track style bike unless you wanted to use a mtb fork...or maybe there is something that exists that i am unaware of

My verdict: Possible, but silly. About the worst "upgrade" you can do. If the frame is 1" and comes w/o fork, you don't actually need to do anything. Just get threaded stuff. If it comes with fork, you can 1) have the steerer threaded by a good shop if it's beefy enough. 2) have a framebuilder swap out the steerer for you. I'd recomend this over threading the existing one. 3) get a new fork

...about the best upgrade you can do IMO.

Only topped by converting to Ashtabula cranks?

This can work with a steel fork, but watch out for one "gotcha" I ran into once...I threaded a steerer for a customer who wanted to convert, then discovered that the threadless steerer had thicker walls than a sandad threaded steerer, and it was not possible to get a stem to fit the smaller hole! I really don't understand what the manufacturer was thinking...

Actually 1 1/8 threaded forks of any type are pretty scarce.

As things have turned out, there are basically two currently viable setups: 1" threaded and 1 1/8" threadless. Everything else is oddball and should be avoided if possible. The market place has spoken.

Good info. I might pick up a Bare Knuckle afterall...

I guess it is not only tandems - I have (I do not know why nor what for) 1 1/8 quill stem for MTB.

One gear, One god, One-piece cranks.

I'm not going into aesthetics, so let's accept the working hypothesis that quill stems look great (not my view but let's play...)
Still, from every kind of practical, functional viewpoint threaded HS and quill stems are inferior to threadless. (Except for ease of adjusting height but even that's debatable.) In some respects, waaay inferior.

You mean the one with a 1-1/8" steerer? So, you can run threadless?

Other than aesthetics, why?

this is a board of aesthetes, there doesn't have to be another reason.
