Bicycle Mechanics - Threaded 1" to Threadless 1"

Hello folks,

I have just came across an incredibly cheap (an oldish) but super racy steel frame in great shape that I would like to put out as my cyclocross/commuting rig with cantilevers. The actual steel fork on it does not have any kind of brake attachment. So I am thinking about replacing the fork with a Surly cross-check. The little problem in here is the headset I guess. The frame still has the old 1" threaded with the quill stem in. I assume I have to remove it all, but can I replace the old 1" threaded fork/headset/quill by a 1" threadless fork/headset/stem? I have already check for disponibility of these kind of pieces, I could have them all... But, will it be possible to make the change?

Thanks a lot to all, and sorry to have asked yet another threaded/threadless question but I haven't been able to find my answer yet

There have been a few different 1" head tube/headset standards, most of which can be fitted to the main ISO standard. http://sheldonbrown.com/gloss_ha-i.html#headset

Chances are a 1" threadless ISO headset should work, but if you don't have the proper tools to remove the old headset and (especially) install the new headset, take it to the bike shop--they should know whether the swap will be straight-forward.

Also, what is "disponibility (http://dictionary.reference.com/browse/disponibility)"? Edit: I looked up "ponibility (http://dictionary.reference.com/search?q=ponibility)".

I don't see why not. On the other hand you can still get threaded forks that have the options you need. And that will not require a headset change.

I've done it before...just need the headset, stem, and fork...not hard at all.

Headset changeout with the new fork is all that is necessary. You will need to remove the old headset, as others have posted, but that is something any good shop can do for you, along with pressing in the new headset and cutting and fitting the new steerer to size.

Thanks everyone....

@ operator, do you know where can I find a 1" threaded fork with canti brake mounts on thw Web? Maybe I haven't look hard enough: I tried a look on Ebay, Pricepoint, JensonUSA, Nashbar (I don't have a very comprehensive bike shop in my town...)

@ JiveTurkey: sorry, I sometimes mistake french words to be almost the same in english (I lack a great deal of practice)... I meant availability :-)

the hardest part is finding the fork u want... seems liek u already have... i just did this switch on my commuter. love it... i'm using a 1 1/8" stem tho... more variety. either us a shim intended for stem or a 25.4 to 28.6 seatpost shim with do just fine with a little trimming

Not cheap...
