How are bicycle rims manufactured?

What makes a good bike hub?
Good-quality bearings, sealed and protected from dirt and water
, are the key to long and healthy hubs. Older or less expensive hubs may use cup and cone bearings, which contain two rings of loose ball bearings that sit in ‘cups’ inside the hub body, and are secured in place by conical nuts known as ‘cones’.
How long does a bicycle hub last?

8,000 miles on average
. This can vary to as high as 18,000 miles and as low as 5,000 miles depending on the surface on which they are ridden and the rider’s weight. Notably, sealed cartridge bearings typically last longer than unsealed ball bearings due to separation from the elements.

How are spokes manufactured?
If bladed spokes are being produced, they go through one final step, called flat forging.
The spokes are fed into a press and a force of up to 250 tonnes forms the bladed profile between two dies
. This cold forming process again cold works the material, further increasing strength.
Where are DT Swiss hubs made?
