| Mar 25, 2022 at 17:30 | comment | added | Sam7919 | (3/3) If the ratio of the two radii is small, then when a bearing ball gets "squished", it will have a larger area of contact with the cone, and the resulting maximum stress (I'm guessing the stress distribution is still not uniform; it's highest in the center, just like a beach ball hitting the sand) will be lower, sparing both cone and cup from potential damage. | |

| Mar 25, 2022 at 17:30 | comment | added | Sam7919 | (1/3) I know you're a 94k and I'm a lowly 3k :-), but I think your first point is not right. If we agree that "nothing is rigid" (engineering.stackexchange.com/a/48869/36266), and that each bearing ball under any load, but especially a 70 kg load inadvertently hitting a tree root (bicycles.stackexchange.com/q/67038/48599), becomes a squishy ball, albeit a tough squishy ball, ... | |

The first bike boom was because bicycles were less work than horses, and also related to emancipation of women. Cars could be viewed as "labour-saving bicycles" despite needing much more maintenance. Cars were the first "assisted bikes" from one viewpoint. | |

Do take into account the fact that people’s tolerance for mechanical faults is larger for cars because one can always just put their foot down a little more. On a bike, we care more about every little source of damage and drag. | |

It is possible to own one car and keep it running with minimal downtime using standard spare parts. By comparison, relying on a bike for transportation means that one must maintain a small collection, not just with different types of tires, but also with redundancy until the difficult-to-find parts are replaced. I know, I know, this is a Q&A site. I should be writing a question instead. Dear reader, be my guest. | |
