Question

Why are oil and grease used by people who mend bikes

Answer 1

Answer:

Grease is a heavier, waterproof lubrication which is generally used in places on the bike you don't take apart or see too often. It has two key, but quite different functions: To keep key components moving and free from water entering. To help places of static metal to metal connection from seizing up.
