Trek Madone 3.5 headset replacement.

[EltonFrog]

I would like to change my headset on the above bike, I've done the bearings once before so I know how, but I want to change it to a Chris King headset but I do no know which one to order. Can anyone advise please?

Apparently it's an Integrated, cartridge bearings, sealed, alloy, 1-1/8" top, 1.5" bottom, which makes no sense to me, and I can't find anything on CK site that is obvious.

Many thanks.

No point. It's integrated, so you've just got cartridge bearings to replace. If you can get the corresponding equivalent of the likes of SKF. The cartridges should have the key measurements printed on the outer edge.

OK, thanks.
