I'm cleaning out most of the bearings on my new (second hand) bike.
I'm replacing the grease inside the pedal bearings and I was wondering.
How many ball bearings should be inside? I thought there had to be just enough to fill the full circle, but a friend of mine told me I should fill the circle to its fullest and then remove one ball.
The reason, he said, is that else there is to much pressure on the bearings.
Is this true? And is it true for all the bearings (say, the ones in my hubs)?
And also, I'm putting vaseline (the yellow heavy-duty variant) inside the bearings – is that a good idea?
