On-one Inbred frame... What headset?

[Kermit power]

Afternoon all,

Bit by bit, I'm building up a bike for one of my offspring based on a 14" On-One Inbred frame. I'm fine on pretty much all of it, but I'm buggered if I can figure out which headset to fit to it!

This is their headset page, with a grand total of 41 different products!! Granted, some are spares and spacers, but even so, I'm baffled as to which one(s) are right. He's only light, and he's likely to outgrow the frame long before even the cheaper end of the market would need servicing or replacing, so cheap is good!

The actual frame is this one here. Any suggestions welcome!

You'll be fine with the smoothie regular. I had one on my inbred & did lots of xc with it & had no problem. I weighed close to 18 stone at the time so will be fine for a much lighter rider.

Yeah, my secondhand frameset had the smoothie regular on/in it, it's fine.

The FSA "The Pig" headset will fit for the least money.

Thanks, chaps!

I got an FSA Orbit MX with mine. Think they are less than £20 from One-One
