I wear kneepads pretty much every time I ride- never found any reason not to, tbh, and plenty of reason to. It doesn’t take a lot to ding up a knee- not talking about permanent damage but I don’t like spoiled rides and time off the bike.
But my shinpads are purely for dh- never found a set I’d be happy to wear all the time. And yes my shins look absolutely haggard.
is wearing armour causing more serious injuries with a false sense of safety and folks riding above their abilities .
Almost certainly causes some (then again, wearing helmets almost certainly causes some injuries too 😉 ) But on balance I’d doubt it’s a negative effect.
