I was out on my first ride of the season, solo riding which I prefer. Nice day, enjoyable ride, and having fun. I came across a group of 3 men, one was on the phone and the other two told me he had put two tubes in his tire and blew both as soon as they took off.
I knew the problem as we ALL have had this problem. We forget to check the tire for glass, metal or some pointy object. We took off his tire and I found the metal piece quickly. Lucky I had extra tubes and CO2 and was able to help get this tire back on and get the rider on his way.
I often wonder as I pass riders on the road, do they have a tube and an inflation system that they can actually use if need be?
I told the fellow whom I helped with my supplies that he was now obligated to pay it forward and help the next guy he sees stranded on the side of the road.
But if you are reading this and just home from a great ride, go out to your bike and pull off your little supply bag. It should have 2 tubes, 3 or 4 CO2 cartridges, and a tire lever that can actually do the job.
Practice changing a tire at home, do it in your yard standing up as that is how you have to do it on the road. Use whatever inflation system you have and practice with it. If you only carry a small pump make sure you can inflate the tire to a good pressure.
Pictured are my bag and supplies. I have plenty of C02, two tubes in plastic bags to protect them from punctures, a Pedro tire lever, big and strong, tools and some extra washers and screws for my shoe cleats. This all fits into my rather small useful bag. Also suggest buying your CO2 online, way cheaper than what they charge in bike stores.
ALWAYS carry a cell phone, and ID such as an expired driver's license. If you are biking with a friend or wife or hubby, make sure you EACH have a phone. You can get separated and then the phoneless spouse or friend is stuck. I have run across this scenario many times.
