it opens faster and easier
Cartridge bearings offer advantages over traditional loose ball bearings in bicycle components because they are sealed units that require less maintenance, provide smoother operation, and are easier to install and replace.

Sealed cartridge bearings in bicycle components offer advantages such as increased durability, reduced maintenance needs, smoother performance, and better protection against dirt and moisture.
Rolling friction occurs when moving parts have ball bearings. This type of friction is lower than sliding friction, as the ball bearings allow the parts to roll smoothly over each other with less resistance.
Precision bearings, on the other hand, are highly accurate in terms of material quality, consistency of finish and diameter, and repeatability of tolerance levels.

Yes, in the seals around the bearings, in any suspension element you might have, by the brake pads and so on.
When parts have ball bearings, the friction that occurs is rolling friction. This type of friction is lower compared to sliding friction because the ball bearings allow the parts to roll past each other with less resistance, reducing wear and improving efficiency in mechanical systems.
