I believe what you're describing is the "Rim Tape". The rim tape covers up the holes in the rim (wheel) that the spokes attach through. Without that tape covering the holes, the innertube (air chamber) will be exposed to holes and sharp surfaces that are likely to cause another flat tire. If the rim tape is torn in one spot, but still covering all of those ...

There are a couple of types of rim tape available: Cloth - This has a glue backing and is very long lasting. If you need to replace a spoke nipple, depending on the age of the tape, you will most probably have to also replace the tape since it will no longer stick to the rim. Rubber - This is continuous loop of rubber (stretchy) and the stretch is what ...

This is usually ok. as long as it has strong enough adhesive to stay in place. It's better to overlap it, of course, but as long as the spoke holes are covered it should be ok. A bigger issue is that usually, when the tape comes up short, it means that roll was designed for a 26" wheel, and is going on a 700c rim. If that is the case, make sure the tape is ...

You should be fine - the primary purpose of rim tape is to protect from the spoke holes. If you are at all concerned that there's some rough in that small gap, a small peice of duct tape to bridge the gap would probably suffice (when isn't duct tape the answer?). I wouldn't waste a roll of tape for the sake of a single millimetre!

The usual cause of inner tubes exploding while being inflated is that part of the tube is pinched under the rim, or was damaged by a tyre lever while you were fitting the tyre (but manufacturing flaws can happen - I once had a puncture in a tube next the stem where it was difficult to patch, and my spare tube failed at the same place as soon as I inflated it ...

When I bought the carbon 50mm wheels, I put on the yellow velo plugs. I had more plugs than necessary and I made sure the plugs fit snugly into each hole. Some plugs didn't. But I had enough plugs to choose from. Its been over 2 years and I have not experienced any loss of plugs. During those 2 years I had numerous punctures, front and rear and a change ...

Rubber rim strip is pretty stretchy stuff--and you want it to fit snugly! Therefore, if buying rubber the diameter of your rim strip is not nearly as important as the width. It should cover all the spoke nipples and/or the large holes drilled for the spokes, and fit well along the rim. That said, your local shop should have some in a size that fits 26" rims ...

There are advantages to all of them, but tape has always been my preference. I've used velo plugs, but in my wheels the incidence of loss was too high. They lasted me less than a year, before I lost all the extras, and went back to tape. I don't use rubber rim strips because the rubber degrades, and they move around too easily. I prefer Schwalbe high ...

I just recieved veloplugs today for the wheels i am building and i must say that i like the design and the fit. I measured the holes inside the rim and they were exactly 8mm so i went with the same 8mm model plugs. If you dont know yours you will definetley have to remove your tire and tube and peel back the tape to get a good measurement. I weighed the tape ...

You left out reinforced plastic/rubber type strips. Kore Chastity Belt strips are my favorite and rated for 140psi. Very durable. FSA, Origin8, etc also make this type, available in many common sizes. Price ranges from $2.50 - $4 each. I do like cloth tape, but the adhesive can dry out (even before purchase). Velox is $5 a piece at my shop. Rubber rim ...

Innertube failure can be caused by a variety of factors, and it is usually possible to determine the cause by examining the failed innertube. You mentioned: "In the last week, two innertubes on two different bikes exploded". If it literally exploded into many small pieces, then you were probably the target of a saboteur. :) More likely, the innertube has a ...

You can use fairly cheap substitutes: My preferred one is the very same old inner tube, cut to fit. Cut a stripe a bit wider than the rim, and it's lenght should allow to go completely around the rim. Use patching glue to close the loop. the loop should be tight enough so it keeps in place by it's own tension. To properly glue the ends of the rubber, use ...

Yep, it's "rim tape" or a "rim strip". The "tape" version is a bit like medical adhesive tape, while the "strip" version is generally a circular strip of rubber or stretchy plastic. The purpose of the strip is to separate the "inner tube" (your "air chamber") from the spoke ends and the holes where they reside. The spoke ends are sharp and will cut ...

tyre manufacturers recommend to change the rim tape each time you change a tyre. Plastic rim tapes actually get damaged after a few thousands km under high pressure and I hate rim cloth that get soaked with water under rain. I have been using veloplugs for a year now and I am very happy with this system. Easy to install, light weight, and above all very ...

Or you can use cheap plastic adhesive tape, usually two to five layers. It's cheaper and lighter than any of the above, but it doesn't last especially long. It helps if you de-burr and round off the edges of the spoke holes. After a while you will start getting punctures where the tape has given way and the tube gets cut by the spoke holes. I was surprised ...

Rim tape can actually slip, slowly, due to heat and/or mechanical stresses (rolling of the wheel, twisted tube), but would be my choice, since they're not elastic (accept high pressures well) and can't damage the tubes. Rim strips are very fine, but their edges might become hard with aging, and I have had some flats due to cuts in the innertubes caused by ...
