I need some new bearings for my headset.
But I can't work out exactly which FSA headset this is and so I'm struggling to work out which bearings I need to buy to replace the current ones.
I can't find any numbers on the bearings and it just says FSA ACB on the cups.
Any help would be appreciated!

Can you measure them -put the dims in here:
http://www.bearing-king.co.uk/how-to-measure-a-bearing.php
and then you'll have a bearing code.
ACB = Angular contact bearings.
Tried here? - http://www.fullspeedahead.com/category_list/53/HEADSETS
I couldn't find any like this on the FSA website, with an integrated top and external lower.
I'll drop the forks out this evening to measure the bearings.
You need to measure the bearings it also depends on angle as well, common ones are;
1" 1/8
36deg x 36deg OD 41.5mm TH-872
36deg x 36deg OD 44mm TH-871
36deg x 45deg OD 41mm TH-873
36deg x 45deg OD 38mm TH-373
45deg x 45deg OD 41.8 TH-870
1" 1/2
36deg x 45deg OD 51.8 TH-073
45deg x 45deg OD 46.8 TH-970
45deg x 45deg OD 52 TH-070
Easy is't it? .2 of a mm difference FFS! 😈
When I had the same problem I carried them into my LBS who pulled out a bunch of bearings they had and let me have one from a tub of spares (new, still in the bag) for a couple of quid. I could then read the numbers for future reference... I didn't, but I could have 🙂
Might be worth a go if you are still stuck?
I did actually try my local Evens yesterday, its my closest bike shop. I went to get some suspension grease so I thought I'd ask whilst I was there. They couldn't help me with either 🙁
