What tyres are on?
I´d consider Time pedals, carbon saddle and lighter carbon seatpost(cheap and good one: https://www.aliexpress.com/item/UD-ligh ... 3c00JL8oKU )

Sram Red groupset will do that...or maybe a frameset change? :-)

Custom integrated saddle/post combo from Berk and you’re at 6.8kg for less than 500€

Assume you already cut your extra seat post length (if any)? Aside from that, nothing's free.

First place is tyres: gatorskin is 240g each and rolls poorly. Going with GP 4000SII will save 60g for both tyres, for not much money and make you faster on a flat. I could not peek inside the tyre, but some lightweight tubes might offer another 40-50g of weight savings, and are cheap as hell. Alternatively, if the wheels are tubeless ready, go tubeless - for a similar aggregate weigh saving, and even better rolling resistance with something like Hutchison Galactic TLRs 11 Storm.

Saddle is probably next. Berk will save you c.145-150 grams. Not cheap, but not cost-prohibitive either. Bontrager XXX is pricier but similarly featherweight.

Smaller stuff: you can get lighter bottle cages at sub 15g each, and titanium fixing bolts for another 5g or so. This almost free, but will be unlikely to save more than 10-15g in total.

I think all that can already get you to c. 6.8kgs total. If you are looking for more - probably look at pedals. This is poor bang for the buck, but probably 50g of savings to be found in total, at varying amounts of expense.

Next time you replace cables, I'd look to some lighter weight options (savings aren't much, really). And next time you replace the chain, use DA, rather than ultegra - it's a teeny bit lighter for a teeny bit more. Cassette has more weight savings on offer but at a steep premium.

I do and yes it’s stiffer but I didn’t find it uncomfortable and my saddles usually don’t come padded.

I do. I never trusted aliexpress/ebay carbon goods before, but after I tried saddle, seatpost and bottle cages I think you could find good stuff for the price. Saddle was 109g without padding and more comfortable than my Prologo Evo or Selle Italia SLR(but it depends on your butt).
Seatpost is about 130g(27.2mm) and after few thousands kilometres still doing well.
The point is to choose reputable seller and don´t buy the cheapest stuff over there. Even though I would avoid a carbon frames, stems, or handlebars on aliexpress, some items can easily shave a lot of weight from your bike if money is the object.


About tyres, you didn´t mention width, but 25mm tubular Gatorskin is about 320g, so if you choose, let´s say, Vittoria Speed, you could easily save about 220g on both tyres. But Speeds don´t last long, I am currently riding heavier Corsa G+. They are about 280g each, but still light and very fast. But lighter tubulars can be find too, some of Veloflex for example.
