Default frame fork headset

Not sure what a fork for integrated headsets implies. Will a fork for integrated headsets allow you to slide the separate metal fork crown race down the steerer tube? Or is the fork crown race already formed into the bottom of the carbon fork so no separate metal piece is needed? Or does this "for integrated headsets" fork just mean it looks best with frames with integrated headsets because the fork crown is formed so it all blends together well?

The fork I am looking at for this frame is the one below. Nashbar full carbon road fork. In the description it says "for integrated-style headsets".

Huh. When I click your link I see a regular 1-1/8" carbon
fork with enhanced marketing ('slice through the wind').
Copy says 'for integrated headsets' but the crown diameter
is not shown. Image doesn't look unusual.

Standard 1-1/8" threadless headset, not integrated,
internal, hidden, oversize crown or anything frenetically
outside of normal. Sealed cartridge units run $40 up here.

Many modern headset systems use a steerer with larger
bottom. Your linked fork doesn't appear to be that type.

It seems the description 'for internal headsets' means 'fat
top of fork crown' rather that 'larger bottom bearing' but
again there is no crown seat diameter specified.

Default frame fork headset

Thanks everyone. I now sort of have a definitive answer. The picture is of a fork with a large crown designed for bikes with headsets that fit right into the headtube, no external cups. That may pose a looks problem with a too large crown and external headset cups. Andrew says the picture shows a steerer tube that is the same diameter top to bottom and takes a separate race. Like regular forks. He thinks the description of "for integrated headsets" means the race is formed into the bottom of the steerer tube and will not accept a separate slide on race. Fork like this will not work with a regular headset.

After learning this and seeing the pictures again, I may just go with one of Nashbar's other forks that is designed to accept regular headsets and looks good with regular frames. Has a normal looking crown. It will have an aluminum steerer instead of carbon. But I doubt the extra weight will affect me too much.

I didn't say that.

The fork shown takes a standard headset crown race. The fork
itself is big on top, which may be an aesthetic problem but
not a mechanical problem.

Default frame fork headset

GNAW if you like the stated CF fork

Get on the phone for abt 2PM PCF and call Universal Cycles ( Yellow Jersey prob doesn't stock whatever this is but you cold wait n ask YJ ) and inquire abt

'will not accept a separate slide on race. Fork like this will not work with a regular headset'

but Andy sez no prob anyway but ASK ! UC has a expert 'like' how else could UC sell those head tube system adapters ?

I built alotof my Redline Trekker, a modified, from UC when frankly I know dung abt mating components
