Howzit, I got a shimano; OCTOLINK/BB and having just replaced it I’m trying to prolong the life of the new BB.I have noticed a fair amount of water got into the space around the bb, with dust a destructive agent. I have a screw hole below the Hub, to secure a cable guide and when i remove the screw after a wash it acts as a drain. Now my questing could i pump silicone in through this screw hole filling the cavity and probably keep the BB a lot drier? The silicone should gel around the BB and should come out as a tube the shape of the cavity on removal. Any comments? Cheers Howard.
