That is awesome Loutre!
Bearings... I did a complete bearing inspection of mine when I bought it. They all looked fine, shy on grease in a few, but I replaced them all for safety's sake. I think this may be a worthy endeavor in terms of preventative maintenance. But it depends, sure plenty of people have not had failures, I just do not want to right a ride report in which I get stranded somewhere in Oregon and get attacked by drunken otters after I throw a wheel bearing.
