Removing Canyon Acros headset - what do I need?

Hi,

I currently have a Canyon road bike with Acros Ai-70 headset. Although it works fine, the headset adds a lot of stack to the setup. I want to replace it for a ‘conventional’ headset assembly. Canyon offers a kit, but it has been unavailable for months. So, I am now looking of buying the parts myself.

Does anyone have experience with this? If I am correct I would need two parts:

It’s rather difficult to find these parts for 1 1/4 fork tubes, especially the bearing cover. I am also worried if the bearing cover would fit properly. Canyon sells a cover from Acros, but this does not seem available at the Acros site.

Thanks for the help!
