Howdy - building up a new bike for the upcoming season.. WIll be going full Ultegra Di2 setup - 46/36 gearing on the crank.. Lost as to if I should be going Di2 Rear Der either SS (short cage) or GS (mid cage) for the rear derailleur.. I don't see myself running anything more than an 11/28 rear cassette..
Appreciate the help in advance..
SS for a 11/28. GS for anything larger!
