- In addition, these patterns are apparently patented!? The guy I talked
- to at Phil Wood suggested that they were worried that Shimano's lawyers
- would come after them if they used the same pattern on their casette hubs.
- They came up with a different, but compatible, pattern instead for the
- part that will mate with Shimano cassettes. (Parts will be available to
- make the hubs work with Shimano, Campy, Suntour or Mavic cassettes.)
-
- Sorry to keep referring to my trip to Phil's, but I learned a lot there
- and it keeps seeming relevant.
