I have a Sturmey archer freewheel and a tricycle hub. Both claim to be 1.375″ x 24 but they don’t seem to fit. I’ve forced it a turn or so (you can see the anodizing has come off the hub) but it is just way too tight and not going on properly. Any ideas? Might one be some crazy metric size that is close but not close enough? I really need to use the hub, happy(ish) to buy a new freewheel.
