one more tip I learned is to put your extra new tubes in a baggie with a little baby powder squirted in... then when you put the new tube into the wheel (DO inflate a little as suggested so they go in easier and hold shape) the rubber of the tube doesn't stick to the tire or wheelset... slides ride in, smooth as a baby's bottom...
of course, you also smell good for the rest of the ride...
glad you figured it out... it's an important skill to have...way to go!
There is a fine line between "hobby" and "mental illness".
