Help with forks and headset

[Spleeble]

I need some roadie wisdom

I'm currently sourcing all the bit to build my first road bike (Giant OCR) and don’t know much about the forks and headset. By the looks of what is in the head tube it has got a semi-integrated headset. I guess that these still use a crown race and top seal(?), If so then I’m missing these bits. Will My LBS be able to source new ones or is it going to be a new headset? I also need a set of forks, I would like to have some Carbon ones but have a tight budget so been looking at fleaBay and getting a bit confused. Can you use any fork with a semi-integrated headset or are they designed slightly differently?

Any fork should fit and your LBS will be able to supply a suitable headset.

Like has been said, any 11/8" fork should fit provided the steerer is long enough, i would just buy a new headset, they arent expensive.

Thanks guys, looks like thats one more thing to add on to my budget build.
