I did not lube them up before putting them in because they come pre lubed. Now, I played my first game with them last night, and I felt so uncomfortable with them. I feel like i was skating on glue. It seemed as if I needed to push twice as hard as with my ABEC 5 bearings. Can anyone relate to this? or does anyone have any suggestions as to why they feel this way?
Thanks alot.
