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 ...

This particular rim strip absorbs color from everything, and it is not a problem. Mine have turned green in use from something leaching from tubes. In general, rim strip should be replaced if it splits, stretches deep into the spoke holes or exposes the spoke holes. Discoloration happens, but since rim strips aren't usually visible this is not much a ...

That is poorly built and unacceptable (in my book) as a paid for product. If all of the spokes are protruding some, and several more than others, it means that the wrong length spokes were used. The reasons for this may or may not be the wheelbuilders fault, it's possible that some component of the wheel build had incorrectly listed sizing and the spoke ...

Thats just the adhesive from the old rim tape. Get a cloth and some rubbing alcohol and rub away, and it should look brand new.

I'm not sure why this question needed four paragraphs to explain, but I'll indulge it. However, I want to point out that the most effective decision is whatever results in a reliable tube using the least amount of time, money, and effort to accomplish. That should be obvious and not need to be pointed out. That said, I would personally buy a new tube and ...

I have never heard of anything like this, and here are my thoughts on why this concept has not been made: My guess is that suspension at the rim and outer end of the spoke will effectively re-tension the spoke every time the rim rotates. Suspension only works when it has room to move in both directions, and also has a damper to resist oscillation. We know ...

I would recommend replacing rim tape with a modern plastic one. You could inspect the existing cloth one, but then you would need to remove it to inspect the spoke ends. Cloth tapes often don't survive removal. When the tape is off, inspect the spoke ends and the nipples. If one is sharp, use emery paper to remove the burr. Do not use a file: a single ...

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 ...


6

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've had rim tape before that didn't stick to the rim, but did stick to itself - which is all that matters really. As long as the rim tape won't separate from it's ends, it's doing it's job, plus the valve will stop it sliding around.


5

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 ...

The short answer is yes. Tubeless tape will support using a tube just fine. Tubeless tape does not stretch (much) so the indentation at the spoke holes is very minor. Remember it is holding back the same force per square inch as regular rim tape, if it gave way the edge of the spoke holes would cut the tape and the tubeless tape wouldn’t be doing its ...

These are pinch flats, also known as snake bites. For more info, you could have a look at What are pinch flats?, Best practice for patching snakebite pinch flats on skinny tubes and Is there anything I can do to prevent snakebites (pinch flats)?

Having looked a bit closer, I see these are tubeless specific road wheels. These shouldn't need a rim tape at all. Just, make sure no rim tape ist mounted, stick the valve in, screw it on and mount your tires. PS. This has complete instructions on page 10. http://www.dtswiss.com/Resources/Support/WHEELS/WHEELS-User-Manual.pdf

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 ...


3

While I dont like the throw away and not repair philosophy these days, I would say that 6 patches are more expensive than a new tube. Mine, at 1.50 euro the piece, are not best quality but have been enough for thousands of kilometers. As for patching, I believe that if you patch properly no spoke should move the patch. In any case,the hole should not be ...

As long as it covers the back sides of the nipples and isn't interfering with the bead you'll be fine. The tape is just there to protect your tube from and sharp edges, getting worn through over time or blowing out down a spoke hole. See Sheldon

If the rim is tubeless (fully sealed) and the tire is fully tubeless then correct you do not need to use sealant. Tubeless ready tire then you do need to use sealant. A benefit of the sealant is to also repair small holes. Fully tubeless is a heavier tire. Tubeless ready with sealant is more common set up. Some tubeless rim manufactures such as Stans ...

It appears to be over-stretching of the material the inner-tube is made from. Excessive stretching causes the material to thin out and fail. I've experienced this type of puncture on my mountain bike (Mongoose Blackcomb). My tires are at least twice as wide as the rims and I imagine a cross-section of the tire-tube-rim assembly would look a lot like an ...

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 length 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 ...

For getting the size correct, I stick coins into the rim until I get a combination that barely fits in the slot of the rim. Then measure the that stack.

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 ...

I’m pretty sure the wheel size you quoted is what’s written on your tires i.e. ISO 622 rim (aka 28”, 700c) with a 37mm wide tire. You need the internal width between the flanges of your rims to know what size rim tape to get. This is easy to measure with the tire and tube removed. I.e. 22-622 rim tape is for ISO 622 diameter rims with 22mm internal width....

Tire manufacturers recommend to change the rim tape each time you change a tire. 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 ...

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 ...

One way to get tears around the valve stem is by not supporting the pump head and stem while you're pumping up the tire with a frame pump (the kind where you are pushing on the stem as you pump up the tire, like in the photo below). Notice the way the person's left hand is holding the pump and the rim. The idea is to stabilize the head of the pump so that ...

Low tube pressure and similar dips, I have had it, and it caused cut, sometimes double cut, when hitting a curb or other crush on the pneumatic. Those made the air in the tube go out really fast. I changed rim tape and now keep pressure high, i e pump the wheel more often.

If you can see the end of spoke going out of the nipple, you should polish it with a rasp. If you do not see it, but feel with your hand, the tape will be enough (if it put right, as Batman wrote).

It depends on the rim design. Generally you want the tape to cover the spoke holes, but only just. Measure the width at the bottom flat of the inside of the rim. Or you could get Veloplugs, these are plastic inserts that snap into the spoke holes and are both lighter and less hassle than rim tape. http://www.togoparts.com/articles/article.php?artid=201 ...
