You probably have double rims....meaning there is the normal rim, and then an interior support rim. This means the valve stem is really locked square...so if you twist hard on the tyre, and the valve is right above the tire that is touching the floor.. the tyre will bend, but as you have double rims, the valve stem stays perfectly straight. If you had ...

In addition to Criggie's suggestion, if the hole in your tube from your last flat is facing the tire, when you get your next flat; remove the tire/tube together from the wheel, put a mark on the tube and tire with a ink marker to record the position of the tube in the tire. When you find the hole in the tube, you will be able to correlate it to a spot on the ...

I've tried all of the things mentioned in the other answers here and still had problems. I eventually found a solution that worked well for me. I made a little "patch" to reinforce the tube around the valve. I cut out a piece of an old tube about the width of the tire, maybe a little smaller. Then, I cut a little slit in the center, just big enough to push ...

I’ve been riding bikes since I was 5 and didn’t own a car until I was 32! As a young adult living in San Francisco, my bike was my main source of transportation and recreation. Also worked on my own bike at a shop called the Freewheel. And I’ve never had so much trouble riding my road bike in my life. Tires aren’t exactly rocket science! And I wonder if one ...

I had this same question so I did some looking around. Here's what I picked up -- The simple formula for figuring out which tire works for you. Take the amount of contact area of the tire on the ground and multiply by PSI you have in your tire. So, the "area" (width times length) of the tire along the ground, multiplied by the psi. So, 2" of tire down ...

A bit late getting onto this, but I am looking at exactly the same problem. It is like under high pressure (110psi in my case) the inner tube is pressed out through the spoke hole and I guess becomes so thin it bursts. It cannot be a spoke puncture as the tape is still ok with no signs of being punctured. I have ordered high pressure 120psi rim tapes and ...
