Can I use Dura-Ace 7900 cassettes with 7800 group?
Will someone please tell me if I can or cannot or even should-not mix a Shimano Dura-Ace 7900 set of 11 - 28t cassettes with a Dura-Ace 7800 group? I have an Ultegra 6600 10s 12-27 set of cassettes with Dura-Ace 7800 shifters and derailleurs (short-cage rear); can I switch 6600 for 7900? I'm using a set of Shimano's SL Ultegra WH-6600g wheels; which are specific to 10s cassettes.
If the 7900, 11-28 cassettes are okay with a 7800 group, should I replace my 7800 chain? Will the short-cage rear derailleur work with an 11-28 set?
Thank you! Trent.
