Bicycle Saddlebags

For each of your bicycles, ensure you have the tool saddlebag capable of carrying what you want to have with you for that bike.  Consider the size based on the bulk of the tools and spare inner tube(s).  Consider if the saddlebag will need a quick release to avoid theft when the bike is parked or if the saddlebag can stay on the bike most of the time.

The more you pack and bigger the tool saddlebag the heavier your bike.
