The headset on my friends Whyte 629 2014 has gone. It is an FSA. The lower portion says 'the pig' on it, however the spec sheet says it is a 'FSA No. 10 upper and 1.5" lower external cup Caged Bearings'.
I could probably just change the bearings and the seals but I'm not sure what I need....
Happy to buy the same headset again, I just don't want to get into pressing new cups in etc.
Anybody know what I need to buy?

Take the caged bearing into your LBS and buy loose balls, "stick" them in with grease. [url= http://www.fullspeedahead.com/products/headsets/the-big-fat-pig-1-5r-headset/ ]The Pig seems to need 7/32 balls (you'll need more than 20)[/url], while the upper may be smaller at 5/32
No idea if it's of any help but my (2013) Whyte 929's headset listed as "FSA Orbit ZS, Sealed Cartridge Bearings, 1.5" Lower, 1 1.8" Upper Bearings" had proper bearings, which I've replace, well the bottom one anyways..
Upper bearing (purchased from Amazon): FSA Bearing TH-873 ACB 36°x45° CC 1.1/8
Lower bearing (purchased from UKbikestore): FSA TH-073 MR110 1.5" ACB 36 x 45 headset bearing
