It is Sunday in Ohio and a beautiful day. I say good by to my Family and go on this fast century ride from Springfield to Cincinnati at my fastest speed using a Trek Hybrid with aerobars but 700 x 38 tires.
I love that bike and have had no flats for at least three years of consistent use.
Well, this was the day. Ten miles into the ride the rear started bouncing and it took my a while to realize that this was a flat. OK, no sweat, I have all the tools and a spare. Sit down and remove tire and tube. The valve stem came off the tube. Hmmm....., must be old I think. Study the inside of the tire. Looks fine. No nail, no glass, no wire. Install new tube. New tube does not hold air. What is going on? Must be the pump. It is one of these small bike mounted pumps. Have never used it. Have never had a flat with that bike.
There come my Family on a Tandem bike. They have another pump. Nope. Tube does not hold air. Take tube out. Two little punctures. What the devil is going on? Use a tube fix kit to repair tube. Nope, does not hold air. Use the Tandem and bike to a LBS, 5 miles.
Closed for the weekend. I give up, out of time.
Use the Tandem to get the car.
Came Home and sit down to find the problem. The wheel rim had two small nicks where the two punctures were on the second tube. It took good lights to see that, peace and quiet to feel that. Used a file and emery cloth to fix it. How did the nicks get there? Who knows? I don't.
Now back in business.
I know this is a mundane and trite story. It may be of benefit to a Newbie or someone like me.
