• Hi all
    I wonder if any of you have experience of this:
    I'm currently using a Campag Record Pista BB in the Bob Jackson - problem-free for a couple of thousand miles, but not much of that has been in truly wet conditions.
    How vulnerable are these unsealed BBs? The bearings themselves have their seals, but apparently only outer ones. There are no external seals. I have a Centaur BB that I could put in instead (as I'm doing some other work on the drivetrain anyway) if advisable.
    Thanks.
