Broken wheels don’t instantly result from dropping and climbing curbs. Broken wheels result from poor technique. I’ve been “climbing” (hopping, really) curbs for most of that 40 years without issue. I’ve hopped up curbs on mountain bikes, commuter bikes, road bikes (with 23mm tires), and touring bikes with loads all without issue. I build wheels but I don’t have to build them because of damage.
