Shimano Ultegra 11-32 Cog Cassette
See also Shimano Di2 DuraAce and Ultegra — Weights and Why and Which to Use.
I’m doing all my riding with the Shimano Ultegra 11-32 cassette these days.
I do not like the Shimano Ultegra Di2 rear derailleur nearly as much as DuraAce rear derailleur because Ultegra lacks the quickness and crispness of DuraAce.
Update 25 May 2016: it turns out that DuraAce support an Ultegra 11-32 cassette, at least within some parameters.
But the DuraAce derailleur cage won’t support a 32 cog, and I did not want to get into a custom modified derailleur again as I had done for my Moots PsychloX RSL with Di2.
