I never have much success with superglue, but I would think not; it dries hard.
Contact adhesive - and don't be impatient - follow the instructions.
Only any good if you can keep both surfaces well apart whilst applying glue to one surface and the activator to the other.Superglue on one surface, activator spray on the other
Evo-Stick contact glue will glue leather to almost anything.
You coat both surfaces, wait till tacky then PRECISELY position them as you bring them together. Once they contact you CANNOT slide/slip them into the correct position if they are out of alignment.
Is the item going to be movable? i.e. Is the leather going to fold over a hinged joint? If so you will need to allow a little slack in that area by not gluing along there. So long as you glue either side it should lay flat when the lid is closed but bulge slightly when you open it.
I wouldn't think you need any glue for that - or are you talking about just the bits that fit on the spokes?
Will there be room for a second layer under the spoke trim or will you be removing the original covering there?
