looks like even "low end" spesh carbon is still SL4 spec, that's kinda nice, I was considering an SL4 2013 but they were simply outta my price range, a 105 SL4 is attractive to me. the s-works frameset in orange/black looks good to me as well. also like the roubaix elite, I'll be on the test rides this spring for a new bike so they will get a serious look. will also considering the Rival versions as well
