I have just had a 6 bolt adapter on that fits fine. and just now I tested a (used) halo fix-t cover that also works: https://www.billys.co.uk/english/group.php?prod=huha-fit-t-cover 1.37x24Tpi

Why doesnt my shiny new freewheel extender thread onto a specialized 3 spoke. It gets stuck after 1 turn. I dont want to force it.
Extender should be BRITISH THREAD 1.375"x24tpi : https://www.ebay.co.uk/itm/223104186048 Does this thread pitch standard exist?
sheldon says british thread is 1.370"x 24 tpi and iso is 1.375" x 24tpi.
and is this why it doesnt fit?
