On your build, low end wheels are costing you some on weight, and depending on what they are...I've seen seatposts and stems that are boat anchors.
Built up two frames starting out with 105 but lighter wheels- bars and stem and C.F. Seat post.
The Giant TCR-C came in at 16.7lbs and the Boreas Ignis (Ally Frame C.F. Forks) came in at 15.5 lbs.
Those wheels and tyres can add a lot- and Ally components can be a lot heavier than you think.
Mind you- these are small frames so take that into account aswell.
