Several of 1000 Uses for Old Bicycle Tubes

Step 3 GPS retainer

One of these inner tube slices keep your GPS firmly attached to your home-made GPS rack (See GPS Rack Instructable.), and act as kind of quick release as well. They provide enough tension to keep the GPS in place, yet the GPS can be removed quickly and easily. If you happen to lose a slice of inner tube, it's no big deal, because you have Spare inner tube wrapped around your small bottle of bike lubricant.
