|I have a 2000 Raleigh R500 with 9 speed and shimano Tiagra Shifter. The bike had a flat after I rode it for the first time and I got a inner tube for it. So I got my Cycling friend to fix a tire on my Road bike this past week. She told me that she would let me know if anything else was wrong with it. So let me cut to the chase. I went over to her house to get the 2000 Road bike. I proceeded to ride to a Rally today,and got a flat when I got there. And then During the ride I got another flat while riding it,not to metion one more while I was riding. She told me that she fixed it and filled the tire up to 100 psi. But I got a flat when I got to the Rally. They tried to fix it while I was there. So while I was there she metion to me that there was some metal shavings in the front Wheel. What should I have done to prevent this from happening again? Should I go from 700 by 23 tire and tube to 700 by 25 tire and tube? Or should I have asked her during the past week if there was any problem with it ? What did I do wrong?|

|Think a little different, my friend. A "flat" is not the problem per se. The "flat" is a symptom on another problem. Kinda of like a leak in your water bottle. You can put more water in your bottle, but unless you plug the leak, you'll keep loosing water.
What am I trying to say? You have to find out what caused the leak in your tube. It could be a number of things. A puncture though the tire itself, a spoke puncturing the tube from underneath or even a pinch flat from hitting a sharp edge with low air pressure.
First off, fill your tube with the leak and try to determine where the hole is at. If the leak is on the "outside" of the tube, check the tire casing for foregn objects. Run your fingers along the inside of the tire feeling for foriegn objects as you visually insepct the out side. You may even want to turn your tire "inside out" to look for glass, wires, rocks, etc which may have caused the flat.
If the hole is on the "inside" of the tire, check the spoke bed. Look to see if the rim strip is intact and make sure no spokes are protruding.
If the are two holes, side by side, this most likely is a "pinch flat" (or snake bite in MTB terminology). This is caused by having to little air presure and sticking a hard edge in the road. Just replace the tube in this case.
If you have determined the nature of the leak, corrected it, and are replacing the tube, make sure you do not puncture the tube while replacing it. Try not to use any tools and if you do use tools, make sure you do not pinch the tube between the rim and the tire tool.
I always find the following tip handy. Always place the "label" of your tire facing the drivetrain side of the bike. Make sure the label is also aligned with the valve stem. This way when you find the hole in your tube, you have a general idea where the offending object that cause the hole is.

|One of my greater frustrations in life is manufacturers that put crummy rim strips on new bicycles. Raleigh is definitely on my list in that regard. My recommendation is to take your bike and two innertubes to the place where you bought it and get them to install Velox rim strips in both wheels.|

|I'll second that. A few years back I bought a Bianchi Campione. Two flats in the first 30 miles. Instead of Velox, the wheels had some stupid little strip of plastic in them. I can't believe the manufacturers charge top dollar for their bikes, and then cheap out on a piece of tape.|| |
