I ride heavier so I can get home in case of flat or mechanical problem - tools, spare tube, phone in a handlebar bag, rear rack, lock, computer (well, I can get home without that), pump. Maybe a sandwich. Keys, water, glasses and sunglasses so I can see clearly, mirror.... My Reynolds 531 bike with aluminum parts weighs in at 31+ lbs as I ride it. I expect the bike itself is 25 lbs or less.
I'm not worried. Instead of taking weight off the bike, I've taken it off myself. I've been riding since 2013. If I had taken the weight off the bike instead of myself, the bike would weigh -5 lbs. I've gone back to my weight in 1999, I think. Now, if I could figure a way to get years off my body....
