Yes, although between aero stuff and light stuff I'll pick the aero stuff. Riding fast on flat-ish terrain is more of my forte.
That said, currently trying to lose a couple of kilos and get under 70kg to improve my climbing. Also guilty of upgrading stuff purely to shave off a hundred or two hundred grams off the bike, wearing superlight kit and shoes and throwing extra bits out of my toolkit and trimming the excess bits with a knife. The mini pump is carbon fiber to shave off ten grams off the aluminium one... yeah, weight weenie syndrome 🙈
