lads and lassies its all in your head, oh i must have front panniers to balance my bike rubbish
like how many time if at all you went to the shops with just one rear pannier full to the gullit i bet it made no difference once you start cycling,but put that same load on the front and see what happens.
honest to god burn all your front panniers yiss are been fooled into thinking there a must have you dont need them honestly.
Don't be silly.
Balancing the bike is a convenient side-effect of front panniers that some bikes can benefit from, but it's not the main reason to use them.
The main reason to use them is to give yourself enough luggage space. You keep talking about unnecessary kit, as if that's what the extra space is for. Well, okay, sometimes it is. But you're assuming that everyone can make do with a wispy summer sleeping bag, ineffective mat, minimal spare clothing and has no need to carry significant amounts of food or spares. That might be the case for your body and your tours, but it isn't going to be true for everyone. Some of us need much more substantial gear to keep warm. Some might need half a trailer for our medication (in bulky original packaging, so it can be carried through border control). Some of us are riding for days on end away from sources of food and water, let alone tyres and tubes. Some of us want to carry clothing or equipment for other activities (eg. hiking, business meetings, amateur radio or photography) while we tour.
Panniers, trailers, banana bags, bikepacking, credit card in a saddlebag... There is no one true way. It's all good.
