Prevent Flats by using;
Innertubes with sealant
and always watch the road for debris and keep your tubes inflated to the proper psi. Check the pressure once a week when you clean your bike chain.
But in the event of a puncture, which happens to the best of us, keep the following items in your tool kit;
frame or mini pump.
And remember to always "clean" the tire, inside and out, of debris or thorns otherwise you will only re-puncture that tire again! We have several awesome saddle bags in-stock at Queen City to carry all of these items in.
