My previous bike had BB30, and greasing the bearings on that was simple: Remove the crank, remove the outer seals, remove the bearing seals, add grease, reassemble.
Just purchased a new used bike that has Pressfit GXP, and not sure how to do it here. The drive side bearing looks very similar, and the bearing seal comes off just as easily as on BB30. However on the non-drive side the bearing seal looks very different, and does not come off easily. Do I just need to pull it harder, or is this not removable?
