strip the bearings out and read off their numbers..then order!
 
Looks like the whole bottom race stop block needs knocking out.
Couldn't turn them by hand.
 
The block thingy for the steering limited won’t let you get the bearing out sadly. New cup assembly needed but available direct from acros website.

Hopefully the top one is ok- that requires all the cables/hoses disconnected to replace…

Hateful thing
 
I paid for mine, should have gone for the warranty, but to be fair I put the bike away wet after EWS and didn’t touch it until a couple of weeks ago. Top and bottom both seized solid and replaced

How long since?
Crc know this is an issue, they admitted it.
I'd give them a shout and ask for a refund.

That is terrible! Are the head bearing not greased?
I have checked my wheel spindles and they are greased, not checked anything else yet...
 
They're sealed bearings. Of course they're greased.

But the STUPID internally routed design makes them even more prone to moisture and contamination
 
Sealed or not, if they have no extra grease they will suffer! And as you say the routing design could be causing issues.

Where does it get in?
 
Probably in through the cable routing holes, its then got nowhere to escape and just sits there. There wasn't any obvious grease around the bearing cartridges, there is now though.

The bike did take a good amount of wet riding this year, and was left too long after the EWS which really didn't help matters (was busy riding real bikes and getting the rear wheel rebuilt).

Haven't decided whether to silicone the openings or just regularly clean and keep on top on the maintenance.
 
I have checked mine, and can see where it gets in, not sure silicon is going to stay in place to stop the wet getting in. However, for me being a fine-weather-rider I doubt much will get in, and I will keep the jet washer well away from the bars.

This issue would benefit from a new improved rubber gromet. Anyone know if they intend to provide one?

I had no bother getting warranty on these.
Have you got the new battery cover aswell?
There's more info on Faceshite vitus forum.
 
I've only just bought the bike, so hope it will come with the new cover! Just in case though, what's the difference?
 
New one has a top hat on top bolt which gives a bit o movement and on the inside there's a code, it should end with a +
 
I have a replacement cover: not really a big improvement imho. You can achieve the "movement" (as thebarber added) on the old cover by filing/drilling the bottom holes a little larger.
 
Normally the only source of mud and water into the headset is via the gap between the fork crown and headtube bottom race. That is easilly controlled by squeezing grease into that gap occasionally. The completely stupid and uneccessary new fad for feeding cables through the stem spacers does introduce a much greater opportunity for water ingress which given the constant movement of the bars/cables I doubt silicone would stop. A couple of ideas that may work better include firstly putting a small zip tie ( or similar) on each cable just before entering the headset to act as a drip sill to stop water tracking along the cable; and second, make a neoprene "collar" with a velcro fastener to wrap around the stem spacers.

Just checked the battery and still letting in.
I think the top hat is too long , not allowing the cover to sit tight enough to the frame.
I've cut a rubber screen mount off motorbike down which should allow it to nip up and seal it better.

received my replacement bearing the other day - foc. Not fitted them, but interestingly they came with two new plastic cable-guides-seals, these "should" hopefully stop water ingress.

Was that due to bearing wear, or sent by CRC (in the same vein as the battery door)? I haven't even opened the new headset I got yet, but now I want to to see if I have these plastic deelees too!

if you ask wiggle/crc nicely, as I did, and point out its a known issue, they should send you the kit. I just said mine is now feeling the effects of this issue, starting to notch, please send me a replacement and I will fit them (easy job for me, I am was a Motorcycle mechanic).

BTW I had my bike from Wiggle, they have been great so far, very pleased with them.
(I am aware crc are just another name for the same company)
