You could also drop near to a pound if you put SRAM force on it. There are always huge savings if you buy the SRAM groupsets through eBay sellers.

wheels are a definite upgrade too. 1500g or sub 1500g wheelsets can be found in the $500 range - its a bit of a golden age for light/inexpensive/strong/quality wheels right now... as long as you're not looking for more than 30mm rims.

if you can find any of the new upper end campy groups for a good price you'll save about the same weight as compared to SRAM...sometimes you can get lucky with craigslist with a guy selling off a whole campy group... but the best bet is to buy through the UK dealers that have the groups brandnew at ridiculous prices sometimes.
