Well from the reviews I've read, 2010 Force is basically the same as Red is right now saving a couple of grams in the crank and ceramic pulleys in the RD. The differences I can think of off the top of my head between Rival and Force is BB30 crank and I think the GXP one is a little lighter for Force, carbon outer link on the RD, magnesium lever for the shifter vs. alloy for rival. Probably other things too that I forgot. That being said my Force should be here tomorrow.
