Hi guys, from Cambridge UK. I'm back on my road bike after a 5 year lay-off, and thinking about trying to shed some weight from my bike as a reward for loosing nearly 5 kilos off my own frame

My bike's built around an old FDJ team issue Gitane (Columbus Altec) frame and is 9 speed Durace (circa 99) throughout. Other non-Durace stuff is:
Wheels: Mavic Heliums (original clinchers)
Tyres: Shwalbe F&R with ordinary tubes
Saddle: nice new Flite 135g

Bars: Cinelli Eubios
Stem: Cinelli XA (14cm)
2 x Elite Bottle cages
Currently the bike weighs almost spot on 19 pounds / 8.6 kilos. So...
the question is, if you were to change one, or maybe two things in order to get the best bang for your buck in terms of weight saving, what would it / they be?
Appreciate it's a pretty basic question, so hope you'll be patient with my newbie-ness
