Looks like the pm won't be available until early 2022.

A few questions:

- Will the TT front end setup still include a 5 port junction? Are the TT components any different than prior version? I haven't been able to find any pics so far.
- I see the 12 speed cassette's are backwards compatible to existing 11 speed free hubs. Will 9100/8100 get a firmware update to be 12 speed capable?
