This question might be dumb but if you have a frame that comes with an integrated headset can you change it out for a threadless headset?

Normally yes, but you have to change the fork as well.

EDIT: Ignore this. I must have been asleep when I wrote it. I misread integrated for threaded. DOH!

Am I missing something here? I've always thought that "integrated headset" only spoke about how the bearings sit in the head tube of the frame, not about whether it's a threaded or threadless fork.

I had thought most newer bikes (post '95ish) with integrated headsets were threadless?

What confusion. Integrated headsets have the bearings inside the frame and they are always threadless. I assume what was meant is if an integreated could be changed to a conventional headset and the answer is no.

A frame that takes a conventional pressed-in cup threaded headset can be changed to a threadless model, but of course the fork must be replaced with a threadless model.

Or rather - "not easily". For those inclined to accept mechanical challenges it's possible to cut spacers/shims that will allow you to mount a conventional headset in a frame originally intended for an integrated headset. It's the workaround that allowed me to run an 1 1/8" fork in a frame intended for a 1" steerer.
Who knows, maybe there's even someone selling those adapters somewhere?

How did you achieve it? I am trying to do the same just that it is integrated headset fork into a 1" threaded frame

will a 1 1/8” steerer physically fit through a head tube designed for a 1” steerer?

Yes, barely.

1 1/8” = 28.6mm
ISO 1” headtube ID = 30.2mm

That said, the result won’t be pretty as the bearings necessary for a 1 1/8” fork will require bearing cups that are significantly larger than the headtube. Those bearing cups will also have super thin press fit sleeves (~0.5mm thick) which would be concerning to me as well.

An integrated 1” headtube would be a better starting point than a standard headtube as you could likely support the new larger cups on the original bearing seats rather than trying to squeeze something better the larger steerer tube and the headtube. It would still look weird I think and significant stack height might be added depending on the headtube design.

AFAIK integrated headset are thread-less, the frames head-tube is machined to receive the bearings directly
rather than pressed in races .

I own one of each the Integrated are sealed cartridge bearings that fall out, easily as I found..
the others, pressed in bearing races, are from like Chris King, sealed, bearings made by them..

and ( my others are threaded forks )


Mr C. King Himself has machined a head-tube for frame building that allows the head tube to be thinner for appearance sake..


I measured the Aluminum head tube on my integrated head set bike at about 4.5 cm OD..
