So you're riding along with a full head of steam and "kerPow" you get a flat. Now what? Do you know how to get the wheel off your bike? Yes? Good. Do you know how to get the tire off the wheel? Yes? Good. Did you bring along your spare tube, tire irons, patch kit and inflation device? No? Aaargh.
The basic tire repair kit should include a tube (or two) to fit your tire/rim, tire irons, patch kit, inflation device (mini pump or Co2).
You'll need to know how to take the wheel, tire, tube, off your bike to fix a puncture. You'll also need to know how to get it all back together SAFELY.
If you don't have the basics listed above visit your local bike shop. Even if you don't know how to do the repair at least have the "kit" with you just in case somebody rides by who can help.
Here's to another flat free ride.
