I have noticed that the CeramicSpeed Bottom BracketS for DUB seem to use a black plastic liner where the spindle goes in. In other variants like 30mm you can clearly see the inner metal part of the bearing. With DUB there is a black plastic cover for the outside of the bearing and the hole for the spindle.
Why is the spindle encased in plastic and how do you actually service the bearings? This set up does not correspond with anything in their service videos.
Thanks, Felix
