Adjusting the snubber bearing Stirda 3.2

Can’t find ant reference to this little piece of kit in the manual that came with my second hand Strida. In fact is isn’t even shown in any of the drawings.

Can anyone tell me the correct process for adjusting the anti-skip snubber bearing please?

I think you can refer to this post: :wink:

Is there some sort of eccentric involved or are we just clamping the snubber bearing (actually my bike has two races side by side) in place?
