Shimano have had a patent granted for this design of rear cassette with 14 sprockets!
It matches to a new chain design which was granted for them a couple of weeks ago.
Sprocket spacing is around 2mm, which leaves us frankly puzzled. Whatever they’re
going to use it for, you can be sure they’ve knocked Campags recent 10speed cassette
into the distance…
