Yup it’s the whole lot- it was the whole NX 12 speed groupset out of a groupset box, not even individually purchased items. 11-50t cassette.
This is with the chain installed and chain length adjusted- but the chain length only really affects the position of the lower jockey wheel as the pivot point of the cage is right up around the upper jockey wheel if I remember correctly.
@martinhutch yes it was Shimano 11 speed to Sram 12 speed- everything is replaced though, is there something I’ve missed?
@superficial the b-tension guide isn’t even helpful yet as I can’t even get the jockey wheel far away enough from the cassette to spin the wheel- I’ll use the guide once thats sorted though. Cable routing is definitely correct- I specifically showed my mate this and told him to keep an eye on that for when he puts a new cable on in the future, as it’s a silly mistake we’ve all made!
I haven’t got any pics I’m afraid as I left it back at his place.
I’m more confused at the upper/lower limits just not letting me choose the extreme gears. I reckon I can fix the b-limit with either a longer screw or a different mech hanger
