Headset advice

[mickpc]

I have bought a frame to build up and suspension forks as well. The headset on the frame seems to be larger than on my other frames, do I need a larger headset?

Edit: what measurements do i need to make to make sure it works, I see headsets advertised on ebay, but only the fork tube measurement is quoted.
Cheers Mick

Many frames are headset-specific, now ... consequently. you will need to measure the inner diameter of both ends of the head tube.

You need to know whether the frame uses a "normal" headset or a "hidden" headset, too.
