The problem with breaking down on a bike is that you probably don't carry your 3-inch thick bicycle repair manual with you. And if it's anything more complicated than a flat tire or loose screw, many cyclists will be stumped.
You do likely carry your cell phone with you, however, so a bicycle repair app could be a lifesaver. Offered on iPads, iPhones and Android phones, the Bike Repair app is designed to help you diagnose and fix problems with equipment including derailleurs, brakes, suspension and more.The $2.99 app should pay for itself on the first breakdown.
Now, if there was only a way to integrate a full toolset and spare parts into an app, you'd be really set.
