Headset advice please

[PeteXXX]

My Trek Fuel Ex9 2012 needs a new headset.
Quoted in the blurb is FSA NO.57E, E2, ACB sealed bearings

BTW, I don't have the tools etc to check the angles etc on the bearings.

I've checked the usual suppliers and can't source one.
Any help finding one please?

Just found them on the net.

If you look on the FSA website there should be a technical document to download which will have all the angles and dimensions on it. You can probably then replace it with the equivalent from the FSA 'Orbit' range which will be nicer.

Cheers, I'll check those two out.
