Presently have a 11-28 Ultegra cassette. 10 Speed. Standard 53-39 Tarmac Expert (2010).
Getting a new wheelset and was thinking of putting on a 12-30.

Will this work with this RD6700? I don't quite understand the short cage vs long cage thing. It does not say SS or GS on the derailleur - just RD 6700.

Thanks.
