And I would change them out with each tire change they are so cheap or at least carry a spare.
I know they are boggy cheap Roy but would they need changing out that quickly? I have just repacked the Breva swingarm at 24000miles and they still felt ok, although I think I will replace them next time.
Perhaps your Breva has a separate seal, my Griso does they should last.The swing arm bearings might last the life of the bike with proper greasing.
Can I correct you Roy - they can be a sealed bearing
Tris, I just used the base number from another postYes my bearings were 2RS for, these won't last as long as a dedicated lip seal, would you agree?
Can I correct you Roy - they can be a sealed bearingThe part numbers that John Henry quoted are for deep groove ball bearings and end 2RSIn bearing maker wording 2RS = 2 rubber seals1RS = 1 rubber seal2Z = 2 metal shieldsnothing = no seals or shieldsIts a long time since I worked for NSK but I don't expect things have changed muchTris
I do agree, I think the seals don't seal well enough for their environment .taking one out to grease it hurts more than helps in my experience too.
