For Sale: Slam that stem - low stack headset cover

My frame uses a 41.8mm top bearing, would a 45 fit this

Maybe, depends on the wall thickness of the head tube. Take a measurement, I have all sizes from 45 to 48 in stock.

I found a 45mm cover in my shed and it seemed to work fine so yes I will have a 45x2mm cover please.

Registered as these look perfect for my build.

Have you got black 48mm OD in 2mm and 3mm deep? (Not sure on depth I need so would take one of each!)

Thanks!

Mine's been fitted. Does the job. Heard a nasty crack while tightening top cap down but think it was something seating properly. Do slightly have The Fear now though.

Probably just a bit of grit between the spacers somewhere. I got mine on today too, the Giant headset is sunk so far into the headtube that I had to use a 3mm spacer UNDER the sts cover to get it to not bind up on the headtube.

Any idea what size for cannondale caad 5?

I'd guess at 47×2 given that subsequent generations are that size, but there's no substitute for doing your own measurement.

Do you have a black headset bearing cover to suit a CAAD 10?

Ditto

And @oreos you want 47mmx2mm, will fit fine

Also after a black one for the CAAD10.

Black to fit caad9?

After one to fit a SS Evo Black

I think the SuperSix uses the same size as the CAAD, but best to measure just in case.

Restocking time is coming up, so now is the time to speak if you want non-standard covers, e.g.
@sparky 51×3?
@drøn 46×3 silver?

I'm certainly doing a 44×3 for my Cane Creek 10 EC34, the stock cover looks so wrong. Taking 4mm off the stack height isn't necessary for me, but it might be handy for people with too-short steerers.

Yea, please.

I've got an old 45x2 one but it fell foul of a pretty proud bearing/compressing ring:

the gaps 2.5mm to the top of the head tube so I was wondering whether a a 45x5 one would be possible? (I'd then space it up to get the 0.3mm clearance needed i geuss?) a 45x4.5 would be more ideal but I don't suppose that's asking too much from your machinist?

If the gap is 2.5, then a 45×4 will get it down to 0.5mm which is probably close enough, given that it will be overlapping the bearing. I can do a 45×4.5/5 if you like, you clearly have room to put a shim under it without running out of stack :)

Also, wow, you have a really old one, has it been like that ever since you got it or have you changed either your headset or frame in the intervening 3 years?

Haha yeah, if I remember correctly it was all you had left, truth of the story is I never really rode this frame and when I did I had the stock cover on because I didn't want to ride with my bearings all loose and dangling. I'm gonna start using it again and thought it'd be nice to pick up a more well dimensioned cover because stock covers are purile.

I'll get back with what depth it'll be, measure it again, do some thinking.

I was wondering whether getting a different branded headset might bring it down some, it's a campy hiddenset head tube with a token headset, surely the bearings they use are a standard size? maybe the compression ring could be less tall?

There are different height bearings from different brands, even the ones who get their cartridges from TH Industries, they make 45°×45° cartridges in heights ranging from 6.5mm to 8mm, but 7.5mm seems to be the lowest in a 41.8mm OD.

Has this been resolved yet?

Sorry to hijack the thread slightly, but you are the font of all knowledge @mdcc_tester

Is the bearing cover on an integrated headset part of the compression system? I've got a Ritchey integrated headset and the 'cover' appears to come in contact with frame without touching the compression ring. I can't see how it will ever get tight.

It's almost like the bearing races are too deep. Going to take it to a lbs, but it's bugging me!

You need some shims between the cover and the compression ring. If there's no rubber lip seal at the edge, the recommended clearance is 0.2 to 0.3mm. If there is a seal, it should just touch the top of the headtube. Your LBS should have some 0.25mm shims in their small parts drawer, add as many as are needed to get the clearance right.

Thanks @mdcc_tester - thought it seemed wrong. LBS it is!

45x4.5 please, thanks for your wisdom
