The bike is the Specialized Tarmac Comp Pro. It weighs about 7.9kg of origin. Size 52.

J&L expander/compression plug weight 6.8g and cost 11.99$ , if you prefer better brands than J&L maybe Extralite Ultrastar 3
Latex tube or Light weight butyl tube, from 110g each down to 55-65g each (latex is more puncture proof than Butyl, but need to pump daily)
two wheels 90 grams off, it cost around 20$ each so ~40$ for 90 grams.
other than carbon bar as other comment suggest (i recommend Hylix brand, by the way), check your stem weight, if it is more than 130 grams then maybe worth to change to Kalloy Uno stem, 24$ weight around 110g. And Titanium bolts could bring weight down even further if you want.

I like this https://www.bike24.com/1.php?content=8; ... 30;page=16
Inner tubes, tires, rim tape, skewers, handlebar tape, stem, cassette, compression plug, pedals, seat tube, handlebars, seat, bolts around the bike, cassette nut, seatpost clamp, cable housings.
You might want to consider changing your wheelset. Aero vs climb + carbon vs alloy brake tracks is always a dilemma though. 1300gr alloy clinchers maybe?
And free is to not use caps+nuts on your tube valves. Carry your water bottle in your jersey = more aero + no bottle holders and bolts. Install your handlebar tape sparingly, little overlap and don't cover more than you need.
And never forget to weigh your riding gear. Shoes can weigh a ton. Don't bring a phablet phone. Helmets vary a lot too. 180 - 300gr. No tools and no power bank. Micro emergency pump 40gr, spare ultra light tire 53gr. Water bottles are often over 100gr. If you can replace regularly use PET bottles, just 40gr for 800ml. When changing bolts/nuts/washers don't forget your cleats. I did.
- S-Works Aerofly Bars
- S-works Seatpost
- Roval CL 64 wheelset
- ultegra Cassette
The bike rides really fast and smooth and my strava times have improved on nearly all segments over my previous alloy/carbon bike which was not expected. Still need to get a final weight when I can get hold of some scales.
Of course, you need to know what you want, if you care about performance the lighter is not always the faster. I know people with 1000 grs wheelsets loosing much of their power due to very poor stiffness , with light but extremely poor hubs, etc.
