To remove the wheel. Do you turn the bike upside down? Lay on its side?
I always want to turn it upside down but then I risk scratching up my brooks, computer, mirror, brake hoods, etc.
And then there's fenders to worry about too.
So what's the best way to do it?
To be honest, your situation is rather unique.
YOU are riding some of Grants finest works of art and not some dime-a-dozen carbon racing bike. Someday there WILL be a scratch somewhere and perhaps the paint will fade... if only a little.
If you get a flat the best option would be to get on the cell phone and call Sag Support. If you can afford not one... but two Rivendell's then you surely can afford some sort of Sag as well!
