Your analogy won’t hold scrutiny with a competitive cyclist: newer bikes are also faster given the same rider, even if not as meaningfully as a new CPU.

And modern bikes do make with the need for cable replacement or breakage (hydro lines and electric shifting, while more expensive to service, also require much less of it).

Life tip: Noone appreciates and there's no utility in nitpicking analogies. They're never the actual point of the message and it's incredibly rude and socially inept to lock onto a side quest like that.

idk, the OP is all about the author misunderstanding what they bought. Hence a comment about bikes not understanding bikes deserves just as much scrutiny.

My own life tip: there are plenty of good analogies, so no need to choose use an example you are not familiar with.

With this comment you completely validate izacus (shaky) judgement call: when you write "a comment about bikes not understanding bikes" you are clearly more interested in being rude than pointing out a flaw in the analogy.

We all see that OP does understand bikes in the general sense, indeed the fact you are nitpicking instead of trying to explain one of the many fundamental difference means you think that as well.

To me, it suggests that analogies aren't as useful as we'd like them to be. Either the analogy is perfect, in which case nothing is any simpler, or it's imperfect, in which case you're now distracted by the differences.

They're not totally without value but I find that it's generally better to avoid a analogies. Look for some other route to make the point.

Analogies are a simplification. The problem is not that they can’t capture the whole thing in detail. But that they just don’t stand up to any adversity (because that isn’t what they are for). They are only good for explaining things, not for arguing.

They rely on the recipient going along with the analogy and trying to make it work, not trying to find problems with it. If someone understands the concept well enough to needle the analogy, they probably have a better understanding than the analogy can provide anyway, so it is fine to give it up.

In this case it is neither used for arguing, nor for explanation really, I think, but as a bit of rhetorical flair. The analogy is to an obviously stupid thing to do, throw away your bike because of some easy to fix cabling issue.
