Thanks for the replies folks – to reply to a few:

I’ve had nothing but good service from Nicolai UK and also from Gravity Sports (distributor I used) but not saying others haven’t! I’m also aware that I’ve technically invalidated the warranty by using offset bushes. Bad me! I’m not looking for a warranty replacement – just more curious as to if anyone else has seen this.
IA:
I only have an offset bush on the lower (shaft) end of the shock. What you say makes sense, I think this is what has happened. And no wear on the shock. The bit that rubs the frame is actually the spacers each side of the shock between it and the seatstay attach point.
Think the only thing to do here is just clean it up and move on! The damage isn’t massive so hopefully should be ok. Might look for an offset bush for the top bushing instead though…
