Tire levers, spare tube and a puncture kit.
You might wanna carry a couple of Allen wrenches also. I carry a 5mm one, because there's about 10 5mm bolts on a bike, and I can also adjust my seat height.
Most guys also carry a few bucks and a cell phone.
Carrying much more starts to get too heavy, which kinda defeats the purpose of buying a fancy bike in the first place
I also carry a spoke wrench and a chain tool for emergency on-the-road repairs.
