What should be in the basic toolkit for someone that wants to maintain their own bicycle? I'm looking for something for your average day to day maintenance and tools that I will get the most use out of. Ex: I don't think I need a chain oil/lube/clean contraption...(do I?)
I have some hex wrenches, a few tire levers for changing tires, random screwdrivers, and pliers. Do I need a chain tool? Do I need a bike stand? (I sometimes invert the bike and do tuning that way)
