you should be happy, I have an evo very similar to yours but still almost 2.5 lbs heavier!!
So I got the same wheels on ebay with tires for $1500 but far more used than yours seem to be (on the seller's scale pics weighted 730 gr front with conti competition - 260 gr as for conti website - and valve extender, 1040 gr rear with same tire and a cassete which was lighter then the one Im using now). Im using the same bottle cages - you seem to have very good taste
! bars are 3T ergonova carbon (also got zipp carbon too for the other bike, they are beautiful, got the contour short and shallow). ive got hollowgram compact with MKV chainrings and even my seatpost (149 gr) / saddle (187) / stem (98gr for a 110mm, Im using a 130mm but havent weighted..) are just a few dozens grams heavier than yours.. the only real difference is for the rest of groupset, I got ultegra to cheapen things at this early stage. weight? 13,94 lbs!! Im dead sure the diference from ultegra to red, excluding cranksets is nowhere over one pound! what the hell did I calculate wrong? Id say tires/grouposet correspond to half of the 2.44 lbs difference, so I got still almost 600 gr extra on frame (mine is a 56, heavier blck/wte paint..), tire sealant, garmin sensor, chain catcher, and heavier chromoly sp zeroes.. again, you have 2,44lbs less without spending thousands more.. congrats!
Thanks. Right now in daily trim it sits at 11.5 with cage, and gps mount.
