The R3 SL (2010) with DA 7900 is advertised at $11,800 here at a LBS.

For 2011 they appear to have put the significant design features of the California project into the new R3, the R5, and the R5 CA (which has the flat black paint). The R3 SL has been discontinued. So, if I go with an R3 I get a lighter bike than last year's R3 SL, for a very similar price to last year's R3. Looks like the R5 CA is so light that racers are forced to carry more weight in ballast (just to be legal) than the frame itself weighs. So, I think an R3 will be light enough, lol. Decisions, decisions.
