Can you use an 11-28 cassette with an 11-speed Shimano Ultegra RD-6870-SS rear derailleur (Di2)?
The Shimano website at product seems to suggest that when your largest cog is a 28, the smallest that a cog can be is 12 teeth. Or perhaps I'm reading it wrong.
The same question would apply, I suppose, to an 11-speed Shimano Ultegra RD-6800-SS rear derailleur (mechanical).
FWIW, the setup I'm proposing to use is a 50-34 with an 11-28 cassette, which would not exceed the total capacity that Shimano specifies for this derailleur.
Thanks in advance!
