• Having serviced my BB for the first time after 8,000km I discovered that it doesnt look too tidy...

    Ive cleaned it and replaced the bearings, so that should be fine.

    However, I noted that the surface of the axle had sanded down on the contact points with the bearings - do i need to worry/can I do anything against it?

    Would it make sense to drill a drain hole into the BB shell to allow water to dry/drain our would a drain hole make it even worse?

    Cheers

  • That sort of wear is relatively normal on the spindle IME, doesn't look like it's worn it down at all, so won't have introduced any play.
