1'' threaded to 1'' threadless conversion...

i know there's a hundred threads about this already but i have some unanswered questions...

1.) can i buy any 1'' threadless headset?
2.) do the threads in the frame matter? can i just press the cups right in over the threads?
3.) can i clamp a modern stem onto my threaded fork?

thanks.

yes you can use any 1" threadless headset.

there are no threads in the frame so just remove the old cups and press in the new ones.

you do need a different fork. you can't use a threadless HS on a threaded fork and it will not be long enough to clamp anything to.

I can't believe I made such a stupid mistake! I am going to blame it on using a laptop all week and the desktop tonight

When going threadless, you will probably find it hard to source a 1" stem, however, you can get an adaptor shim to take a 1 1/8th" stem from 1 1/8th" to 1"; some stems come with these, or the can be purchased separately.

I corrected my post, I made a error, I think perhaps just a typo or my brain was moving too fast for my 'hunt and peck' typing style.

you DO NEED A NEW THREADLESS FORK!!! you can NOT reuse your old fork with a threadless HS and stem

A great excuse to buy a CF fork. I know Nashbar stocks them for a reasonable price. Good luck

Yes you can, you need an adaptor like this.
It's also converts your 1" fork to use a 1 1/8" stems without shims.

assuming he is using a threadless headset you can't use this adapter, there is no way to use a starnut and top cap.

I do have sever adaptors like this on threaded headset though, and they work great. they look clunky but the flexability they give you in adjust handlebar position is wonderful.
