You know, fill it up with beer and I’ll help you unloading it. 🤪
Must say that’s some engineering and craftsmanship.
I can take it somewhere where engineering ideas it’s on demand.
I understand what you are saying, sram and shimano have the same fit. Only changes with Campagnolo.
Most Freehubs are either 9-10, or 11sp and you are able to use a 10sp with a spacer between the hub and the cassette.
I don’t believe you will be able to, by my count this it’s a 9/10 speed cassette fitted on the initial pics, so at my best knowledge you won’t. There it’s a change that you can fit a Edco cassette or change the free hub. But I won’t count much on that. Cassette bloody expensive.
I got a mate selling a 11 128gb, or a XR 64
