Please don't. It's bad enough that there's one of him.

What, you never had to replace bearing balls and cones in the parking lot next to a bike shop after only 5000km on a walmart GMC denali cause you didnt feel like working for money to buy a $900 bike from the local bike shop cause you were mad you got hit by a car and were waiting on an insurance settlement? I wash myself up but I still had to touch the grease on the cup cone and ball repackable bearings.

Why he got me off my ass from playing mmorpg's all day and eating stuff people told me was healthy when it was not.
We need more people like this that just post their highly functional lives on the internet for people to watch and adopt.

The solution is to use electric motors and small vehicles for small distances. In north america you're stuck using your car or public transport (forget it outside of a city). Even the bravest leave their bike during winter.
There are some project about hydrogen battery that would bring unmatched efficiency at a reduced environmental cost.
We don't have the technology to do space travel. A human would die due to radiation, even if he survived there is nothing to do. Mars? Yea could be but again we are far from having the technology that would allow a human to live and reproduce to colonize. They might hold for a few months but something will happen and so far from earth there is no instant solution.

Bicycle Repair Man !!!
The Bearings in the Rohliff Hub if you do the annual cleaning Oil Flush and Relube with their All season Oil Could well last that long
so you a million meter rider? how long did that take?
There are Sturmey Archer AW3 hubs well over 50 years old , Sill on the road, in service. thru several Generations of riders..
once again the continuing regular lubrication makes all the difference in the world ..

I always use that 30,000 miles as a reference for service which could very well be decades of use for some riders or if it was me when I commuting regularly, five years.
I expect that the SA equipped bicycles I have will probably take me to my grave.

I'm building a new bike and this bearing question crossed my mind, automobile sealed bearings last 200,000km or more usually and the wheel bearings in the cheap bikes I've ridden only last 10,000km.
Now I want to build or buy a new bike and I am gathering a list of parts. I was settled on the 105 5800 11speed cassette derailleur and shifter, but the shifter won't last as long as a bar end style shifter or more specifically a bar end style shifter mounted on the brake lever eg retroshifter. But shimano 11 speed has a cable rate that only works with new shimano 11 sti. So now I want sram 10 speed, maybe a 10 speed mtb derailleur on a sram 10spd 11-32 or 11-30 road cassette since I believe the cable rate for a sram 10 speed derailleur will work with most shifters.
I was settled on Vuelta Corsa Lite wheels Vuelta Corsa Lite Alloy Clincher Hand Built Wheelset but their made for shimano cassettes. What do you think of these wheels with a sram freehub body if I can find a sram freehub body for these wheels?

What destroys bearings is when the grease gets contaminated with dirt or the bearings are not properly adjusted. If you keep the grease clean you can easily get more miles out of a set of bearings than nearly everything else on the bike. Even better is is you get cartridge bearings, you can simply replace the bearing for $5 each after most likely tens of thousands of miles and be good for many thousands of miles more.

Why not just make a wheel with really good seals, their out there, I just need to find them. Just say your favorite wheel.

You are certainly sending a mixed message, you talk about how you want us to make more and more durable products but the wheels you are looking at are light weight, low spoke count wheels?

If you keep the grease clean you can easily get more miles out of a set of bearings than nearly everything else on the bike. Even better is is you get cartridge bearings, you can simply replace the bearing for $5 each after most likely tens of thousands of miles and be good for many thousands of miles more.

The mixed message comes from Trolls posting thing besides specific brand and model wheel recommendations.
Thank you anyone who named a brand and model.

My problem is on my loose ball bearing bikes I inevitably lose one of the balls during regreasing and have to replace the rest to be sure the set is all from the same lot. Otherwise I could have saved the $2.00 for new balls each maintenance round. I bet if I moved my workbench I'd find a few dozen under there.. I have no doubt that if I did not lose them I could get 100,000k on the same set.

Have bicycled over 3000,000 miles (right amount of zeroes) since early 1970s.
Longest lasting hubs were made by Phil Wood . . . put 80,000 miles on them and then sold the bike and they still spun smoother than Campy. Put same amount of miles on one Phil bottom bracket.
Currently have 40,000 miles on Chris King hubs on our tandem.
Quality pays off in the long run!

What kind of hub is this? My cheap bike has solid axel 10mm dia x 1mm thread spacing and the axels like these on the cheap department store bikes bend and then the cups and cones aren't aligned and the balls wear out fast. My bike is the kind of bike you buy when you don't want to think about making money.

My loose ball hubs are old Miche on a 80s Cannondale and a Campy on an 80s Bob Jackson touring bike, The Miche are very good quality and the Campys are outstanding quality. I bought the Bob Jackson for a couple hundred bucks used. Owned the Cannondale since new. You can get very good quality 80s bikes for not much these days if you look around. I bet loose ball hubs would last about as long as a person lasts, but when the balls are a few cents a piece, most shops toss them out with the old grease and put in new ones with the overhaul.
I broke the Miche axle twice and replaced it each time when I discovered the problem. Both Campy & Miche hub sets have original cones and races but balls have been replaced many times over.
Best wheels I have are on our tandem - Phil Wood hubs and Velocity Dyad rims, 40 hole.

I guess what I am looking for is newly manufactured stuff that lasts as long as 100,000km. I want to vote for quality bicycle parts and if someone makes a wheelset that weighs 1600grams and it can go that far then I want them to have my money so they can build more excellent wheels. The vintage stuff is finite and I want the market flooded with great parts we can keep making. Are any manufacturers copying the design of the old great stuff and making more?

The investment capital is flowing in rapidly to tool-up for your once in a lifetime purchase. Which part are you going to keep making?

Maxi Carr hubs are famous for lasting 50 years and 100,000+ miles without any service to the bearings. None. No big secret. They have double labarinth seals, large balls, and a very small air volume inside the hub. All technologies that have been forgotten in the bike industry.
New hubs have a single baffle, not labarinth seals, so water and grit go right in. Cartridge bearings are not sealed bearings, and sealed bearings aren't. New hubs have small balls, which simply don't last. They have fat center sections with lots of air inside, which sucks in water and grime with every temperature change.
The old timers not only knew what they were doing, they wanted stuff to last. New parts are all about the latest fashion trend. It doesn't need to last if it is out of fashion next week anyway. High priced disposables: how perfect is that?
