  • I can’t get my head around this Orbea Oiz headset situation. The frame is second-hand but new to me. I tried the headset delivered in a bag with the frame, which fits like the pictures below.

    It looks like the top cap is too shallow or the top bearing is too tall. I checked the spec and the bearing is correct, so I bought a new headset specced by Orbea on their website. It fits exactly the same.

    There is nothing in the frame, which looks very clean, to add height to the stack. The top cap and bearing won't compress under load to cover the exposed area.

    What’s going on? Any experience of these frames or ideas?

    Help much appreciated as Orbea’s team are saying I need to take it to a dealer, which is a pain and I expect they’d order in the same headset and arrive at the same issue.

    Surely I’m missing something obvious.

  • Do you need that black cover on top of the bearing, under the Acros one?

    That's what I'm wondering - what's the black blob between the bearing and the cover, some sort of combined collet and seal? You could try a generic compression ring instead, that might gain a mm, and of course #spam https://grafixbyjorj.co.uk/ headset covers come is three different depths to cater for variations in bearing and compression ring height
