Its advised to play through the initial lube job of the pixel bearings. Some take a few minutes, others take a few days. Others still never break in and need to be cleaned. If you can take it, play it hard for a good couple days. If its not up to par by then, clean it. Ive broken 2 pixels in so far without needing to clean them. Still the quietest and smoothest bearings in my collection. And ive got a different bearing in almost all the throws ive got, (15 or so) only doubles are terripin x ceramic and pixels.
