Show Some Love
The bicycle is a beautiful thing ?? art and performance wrapped up in an awesome package.
But they do not roll without the bearings.
You can not steer, roll, or pedal without them.
Can also be used in some computer fans, the entire service life of 3 months.
So show some love, and keep them rolling smoothly by knowing more about your bike from front to back.
If your rotating components are not smooth, have a look inside to see what you can do for better performance.
