QX100 headset: alternative to FIRST BI-3

[veloc_h]

FIRST BI-3 is a combination of locking headset spacer and adjustable spacer. i can't buy the BI-3 (and honestly I'm not keen on this fragile construction) in Switzerland or in Germany:
In https://forum.cruzbike.com/threads/diatech-headset-adjustment.8585/post-161444 the problem solver combination 9970 and 9974 was mentioned. Does it work with the QX100?

That should indeed work in combination with a regular headset. It is pretty much the same combo that is now used on the current T50. Though that iOS an OEM version and not the Problem Solvers brand.

Locking Headset Spacer

Adjustable Headset Spacer

Are you dialing in the fit of your bike and want to get everything set before you cut your steerer tube? This is the part for you! This spacer will let you set the headset preload without installing a star nut so you can fine tune everything first. After installing your headset spacers and stem...

FIRST told me, that the BI-3 is not any longer offered.
Thanks a lot for your prompt feedback, @Robert Holler

which brand/type is used on the current T50?
The problems solver combi is not deliverable (I can order the adjustable spacer online in Germany, but not the locking spacer). There is a shop in the Netherlands, but they don't deliver to Germany or Switzerland.
