Just Ride is a painfully (!) practical guide to cycling without the gear obsession and adding things to the bike while hoping to shave off milligrams. This, as I am burning bandwidth looking for a positively eyelet-infested tour-ready frame.
Tim Crabbe’s Rider and Robert Penn’s It’s All About the Bike are excellent reads too, to help put you in the mood for a long ride. It is Gironimo next.
