11-28 cassette

[paxterg]

Will a 11-28 cassette work with my Dura Ace 7900 rear derailleur (short cage I'm guessing) and standard cranks (39-53)?

11-25, I intend to replace the chain also

The capacity you need is (28-11) + (53-39)
= 17 + 14
= 31

A DA 7900's capacity is 31 according to google.
You're good to go.

Provided the cassette is 11 speed Shimano or Shimano compatible, it will. Would work with compact chainset too (ie as well as the OP's 53-39).
