Here is my project frame.
Essentially Rival, Force and Red shift the same for the Front Derailleur (zero loss), but only Red had zero loss for the rear derailleur.
until i picked up a dura ace 7800 group for $670 i was going to build mine up with a sram rival group however, i was going to use a Red rear derailleur.
Obviously Force is lighter than Rival and Red is lighter than Force.
IMO go Rival w/ Red rear derailler and use the saved money to buy a nicer wheelset than you planned.
