I'm cleaning out most of the axes on my new (second hand) bike.
I'm replacing the grease inside the pedal axes 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 it's 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 axes (say, the ones in my wheels' hubs)?
And also, I'm putting vaseline (the yellow heavy duty variant) inside the axes, is that a good idea?
