Anyone please post up a close up of your headset?
I've just replaced the bearings and have a small 1-2mm gap between the top cap and top of the frame. I don't remember having one before and pretty certain I've put it back together ok (integrated so only 2 bearings, compression ring and top cap involved).
Cheers
Where did you get your bearings?
annoyingly not all bearings are created the same so even if think you have the correct dimensions eg 45x45 they can still vary a lot.
It's really annoying, we have this problem at work a lot and we've started to keep bearings from different suppliers to try and combat this.
Got them from MB bearings online, they certainly look exactly like the ones they're replacing
Hi Yoshimi,
Here is a pic with and without the top on my 2016 Stumpy frame.

Make sure they are the exact same bearings. Specialised use Campy style bearings which are much flatter on the bottom and not quite so deep. Hopefully that makes sense.
Probably the bearings then, we use a bearing supplier for big boxes of headset bearing in 99% of sizes bit none of them 100% match the specialized ones. Almost impossible to notice a difference until you fit it.
Thanks guys, maybe I'm not doing it wrong after all - I'll try putting the old bearings in tonight and see how that fits.
Normal!
Got the same style headsets on my Camber and Epic and both have a gap - even with stock headset or replacement cane-creek one.
Almost looks like the bearing seat at top of head tube could be machined deeper, but haven't had any issues over past 3 years with the gap....

THIS^^^^^
It's so shallow.
I was wondering if I'd dropped a rubber o-ring or something - sealings not exactly great on these things is it

Zooming in on this also shows a gap
It's a Specialized thing. My new Hope headset cap wouldn't fit my Stumpy frame because of this.
I can't see why they didn't machine an extra 2-3mm of depth into the bearing seat either.
Yip mines the same 2016 29er stumpy has the gap never had a problem
Thanks for the replies, makes me feel much better:)

Hope now make two different types of IS41 headset - the Type 3 and the Type 7 (campy style)
The #7 has a deeper cap, I had a gap on my Last with the type 3, type 7 is perfect.
Specialized do say it's Campy style
FYI - must have been the bearings - took the seals off the old ones (they weren't too bad really), cleaned them out, repacked with grease and put back together - no gap! Prob leads me to buy official bearings next time or the Enduro Max ones
