ETALE....ps. Those hubs you have are amazing!!
The rear is just so rare, I cannot believe it exists.
Another odd point about SSP hubs...they 'custom made' spelling seems to have been through 2 generations....
CUSTUM MADE later changed to CUSTOM MADE.
I have never seen the sealed bearing version.
I imagine they were not released in Japan because 99.99999% of superbe pro hubs were used in Japan for Zen Amateur and Keirin, where everybody used open bearing hubs....
