Putting a new chain on my son’s 8 speed bike, using Shimano HG71. It came with a type of quick link I had not seen before (pic) as I usually use sram or kms links. Theory is you slide one post through the rather phallic end, rotate it around and then slide the other post through the hole.Well the first part went fine but for life of me I could not get the hole line up with the other post. After 20 minutes, I

gave up and used the kmc master link that was on the chain I replaced. That took 8 seconds to install. What am I missing?
