What to have in your repair kit:
This is for a basic repair kit- the essentials.
First, you should definitely have a pump. In the video is a morph pump, which can morph out and become a floor pump.
Second, you should have some extra tubes that fit the size of the wheels and tires used on your bike. If not tubes, at least have a patch kit, though you may find yourself with holes to big to be patched at times.
Having a little bit of cash in your repair kit that is separate from your pocket cash is always a good idea. You can use it for patching your tire or for buying something essential you may have forgotten.
Make sure to have a couple tire levers, usually 2 or 3. It can be a good idea to have three just in case one breaks while you are working with it. You will need at least two, typically, to get your tire off.
Having a pair of gloves will come in handy. If you need to do repairs while you are on your way to somewhere nice and you don’t want to have your hands dirty, gloves will prevent that. Grease can be a pain to get off your hands without proper soap.
It’s really important to have a multi-tool that will have your allen keys, screwdrivers, and a chain tool in case your chain breaks.
Having a extra toe strap can come in handy. You can use it to cinch down things if something fell off of your bike. Obviously it can be used as an extra toe strap as well.
A rag to wipe off hands and chain.
This is a really basic tool kit but is great to carry around riding in the city or a place where help and a bike store aren’t incredibly far away.
