• 5% of the price of a whole new hollowtech bb

    A whole new HT BB is typically £15 for a BBR60, a bit less if you lower your standards. 5% of that is under £1
    Obviously, if you could actually save £14 every time you needed new bearings, that would be a good thing, but probably not a good enough thing to justify buying tools and spending the time on it for a typical individual cyclist.
