All the components in a bicycle ball bearing (how they interact with each other)

All the components in a bicycle ball bearing (how they interact with each other)

Radial ball bearings, the most common type in bicycle applications, have five components to them: balls, races, cages, seals, and lubrication. The quality of the ball bearing is determined by any single one of them. Ultimately, any one of these 5 components in your bicycle's radial ball bearings not optimized can lead to lower performance and have to purchase new ones sooner than expected. Especially if you don't use the right kind of lubricant for race day. The lesson here is whether you ride mountain, road, gravel, or a triathlon, take care of your bearings - and they'll take care of you.
