Cane Creak Headset bearings – how do I know which to get…??

Been on Cane Creek’s website and found my headset but have no clue what bearings I need – any one able to help clear it up?

the bottom bearing is an integrated type so the bearings external diameter is 52mm and the internal diameter is 40mm. part number CBAA0006K or CBAA0006S for the stainless version.
the upper is a zero stack so the bearing external diameter is usually 41mm with an internal diameter of 28.6mm. part number CHSS2030 or CHSS2031 for the stainless version.

You star – I have spent 30 mins trying to get my head around this. Cheers

I’ve been looking at this page and trying to work out if it was the 38 or 41mm for the top bearings

It will be the 41mm.

Yeah, don’t give you much to go on!
