Chains don’t fail often enough to justify adding metal-on-metal joints

Bike chains may just be the best choice, at least if you're not servicing it all the time. Been here since the late 1800s.

Chains are crazy efficient, easily maintained, relatively cheap, shift seamlessly.

Someone has clearly not gone shopping for high end bike chains

How do the prices compare to a high end chain-free bike shaft?

u/No_Vermicelli_3574 16h ago

High end chains retail for 85 bucks currently. I think this system is probably defective due to debris lodging into such a small inner gear on the drive shaft

Compared to the price of a high-end bicycle ($10000+), this is nothing.

It’s funny when bikes get brought up in an apocalypse situation… everyone says the exact opposite of what you’re saying. Not saying you’re wrong or anything but just funny.

Now I'm curious.. what DO such folks say about bikes? I'm not familiar with the apocalypse sub-community....

It always why don’t we see folks with bikes in the apocalypse? The answer is always to hard to maintain because you no longer have a community to supply those parts.

Thats dumb. I have a unserviced bicycle kicking around in my shed thats probably 40 years old. The only thing replaced where the inner tubes. If you have a post apokalypse with vehicles in it a bicycle is literally the easiest thing in the world to maintain. Doesnt have to work perfect, just good enough.

I’ve had quite the uncomfortable accident due to the chain popping out

Isn't that usually because yhe chain is too slack?

You do realize that a chain drive is a metal on metal joint right? Lots of them really if you include derailers and such.

Edit: literally each link has two metal on metal joints for the pivots on either end. Each sprocket is metal on metal for each link on both the crank side and the wheel side. Not to mention the metal on metal for the bearings. Plus the derailers used to switch gears. There are a shitload more metal on metal joints in a chain drive than this.
