I found Jimmy’s photos after I posted the message on the forum. I have also been watching his videos, very helpful!
I saw one person screwed a drink bottle cage to the side of their stem, not sure how the manufacturers feel about screwing into the timber (not sure how I feel about it either, drilling holes into my brand new bike!)
I do have another idea which I’ll try out, a non-destructive option. If it works out I’ll post some pictures.
