It’s always a good idea to carry an extra few rack screws on your bicycle tours. These little things are notorious for wiggling themselves free while you spend long hard days in the saddle. With all the gear you’re bound to be carrying, the loss of a rack screw could mean a disastrous end to your bike rack… and your ability to carry any of your gear.
Before you leave home, go to your local bike shop or hardware store and pick up at least two extra screws for your tour. Most bike shops won’t charge you for them… and if they do, it won’t be much more than a quarter a piece.
After you’ve got the screws in your possession, put them somewhere safe inside your panniers (or trailer). They’re small, so don’t lose them.
When your first rack screw wiggles itself free, you’ll be glad you heeded my advice and took the time to collect these few spare parts before leaving home on your own bicycle touring adventure.
