According to magazines:
SRAM Red GXP: 1953g
SRAM Force 2010 GXP: 2097g
SRAM Force 2010 BB30: 1951g
You can get a brand new Force group on ebay for $950 while Red at least will run $1500. Red BB30 isn't out yet so I am guessing it will shave off the same weight as the BB30 option does on the new Force.
