3 spare tubes? I didn't have 3 spare tubes with me on a two-month tour. One spare tube and some patches. Two sets of bibs, not three. Bibs can be washed out overnight and dried by being squeezed in a towel. Two air pumps? When did you last have an air pump fail? And why CO2 if you're takng a pump? Two multi tools? One isn't enough?

There seems a lack of off-bike clothing. Bear in mind that even at 80 miles per day you're only on the bike for about six hours.
