You’re very welcome! As for traveling by bike I just finished a ride from the top of Sweden to the bottom and except for a used up tire, I didn’t have a single mechanical problem. So as long as you make sure to start your trip with a well serviced bike you rarely risk anything, I’d say.

Of course that depends on where you are going though - I wouldn’t go out on a three month trip in the deepest of Alaska without a good set of redundant gear, but traveling in Europe is no problem at all.
