Simplicity and minimalism is everything with road bikes.
Small saddle bag (with multitool, tube, patch kit, gas can), waterbottle on bike.
Anything else (phone, minipump, waterproof/gilet, keys) go in back pocket.
Back pockets bulging with everything bar the kitchen sink is not cool.
Enjoy the ease of it - out of front door, go ride.
None of this filling the Camelbak, faffing with suspension, dropper posts, body armour... Just ride.
