The first thing you need to do is to get hold of a water proof bag to hold all your repair tools in it. With you being on the road, the weather could play its toll on your tools, and should they get wet, they could get damaged and end up breaking.
In order to avoid this from happening, you need to make sure you keep all your tools in a water proof bag.
Pump and tube
One thing that need to go into your bag is an extra tube for the wheel in-case anything happens to one of your wheels and a small hand held pump.
Both of these are essential, and you should always shave them in your repair kit.
Extra snap on chain
You must also consider carrying a snap on chain link in your repair kit. Your bike’s chain could end up suffering any sort of damages on the way, and should you need to repair that on the road, then using a snap on chain link could make life a whole lot easier for you at that point in time.
You also need to carry other items such as a screw driver, wrench and hammer. Also consider keeping duct tape with you, since you never know what you might need in your time of need, with no help around you.
