Q
What are the functions of bearings?
A
-it supports the weight of bike while allowing the wheel to spin
-reduces contact surface area and therefore energy loss
-reduces contact surface area so reduces friction
-reduces friction and therefore reduces wear on the shaft
-replace the worn bearing instead of parent part
