Everyone, at some point or another, has thought during a ride, "I sure wish I had _____ with me." The only way to avoid this is to bring all your tools and supplies out on your rides with you. Probably not going to happen, right? Why not do the next best thing and put a few essentials in a seat bag or a frame pack. Seat packs are also a great place to keep random items to make your friends laugh on your next ride, like perhaps a water balloon or even your pet snake.
