Nah, but it has to be less than 8kg with that kit, probably closer to 7.5kg (start putting Ti skewers, seatpost clamps, ti bolts etc and chopping off excess seat post etc, may get it a fair bit lighter still, but I won't be going that far, I just want the best spec for the money). Not all that bothered about weight other than it not being being a tank, the light weight of SRAM is great, but is a side product really of just finding the best bang for the buck and looks a LOT better than the other groupsets.
Basically my CAAD9 is fitted with Tiagra 9 spd throughout (BB30 BB shimmed to take Tiagra chainset), this groupset is fine and I have been happy riding it (mostly) for the last 3 years , but the amount I ride (~40 hours a month_ and the fact the frame is a nice frame and has a BB30 bottom bracket shell I felt like an upgrade at least to Ultegra with a 3rd party BB30 chainset, so I have waited on my Tiagra parts becoming worn to point of needing replacing (chainrings, cassette, chain) to make the upgrade. But when it came down to it, SRAM can not be touched in mechanical groupset terms within my budget. Ofc, the shifting mechanism is personal preference and I may find I prefer Shimano, but I will live with it, it is something I will get used to and not think about after a few rides.
The Zipp finishing kit is not that light, esp for the money, but it seems stiff as hell!
