It happens all of the time - you are out on a ride and something happens and you say to yourself, "If only I had brought (insert object) with me!" Makes me wonder what kind stuff has either saved someone in a pinch, or stranded someone in a pinch.
A trip to the grocery store is obviously a lot different than a 6 hour epic mountain bike ride, so it is important to adapt to the particular kind of ride you are on, but you or your bike can suffer almost anywhere. There are two main types of aid - bike aid and human aid. So what do you carry? Is there a tool you cannot live without? An ointment that is sure to ease your suffering?
What do you carry on rides? Please comment freely.
Also, I will wrap up the Lion Bellworks contest soon . . . I've been traveling and need to catch up with my email.
