Yes it's great. I had the select on my 19 kenevo and my 20 came with the 2.1 charger fitted. So much plusher than the default damper.
Pretty pricey though, shop around.
I took the fork upto 190mm also and moved this to the 20 from the 19. I would buy a 200mm airspring if doing it again though.
So on the boxxer it's effectively an upgrade to give it high and low speed compression adjustment right? I was surprised to read the compression adjustment on 2020 Kenevo Expert is low speed compression only.
