That looks interesting. Can you tear it by hand? If so, I don't think it's strong enough.
You cannot tear it by hand. It is essentially a poly strapping tape just like everything else. I’ve been using it for over a year...it’s not some revelatory new tape, but IMO it has the the best combo of stretch, thickness, adhesive, price of any of the tapes I’ve tried.

Stan’s/4289 = not as flexible/stretch, weak adhesive if you have to pull up and reposition tape.
Velotape/8898 = thinner, stretchier, but splits when you punch out the valve hole.
Kapton tape = way too thin/stretchy, wrinkles/shifts, difficult to apply.

I like the fact that it can take high temperatures. I melted a plastic rim strip and blew the tube a couple of times.

With Stan’s tape or similar, do you need to wrap one revolution of the wheel or two? For use with tubes.

Two for high pressure tires, one for low pressure.

I'll 2nd the Powder coating masking tape. I've used it on 3 wheelsets, and its been fantastic. No issues for the last 2 years. Its so thin that I do two rounds around the rim with an 90% overlap on the center. It really weighs like nothing. I bought mine on the bay.

Hmm. I was thinking that recommendation from Stan’s was only for tubeless...

I did a single wrap about 300 miles ago, oops.

Okay, I bought some other powder coating tapes to see if they are suitable as tubeless rim tape...

3M 8991 and generic blue poly tape is probably not a good tape for tubeless specifically. It is extremely thin and has very low tensile strength. The tape elongated/stretched quite easily. The roll weighed 160g, which is heavier than a roll of 3M 8896 strapping tape. If you elect to use this tape, be very careful not to pull too hard...use at least 2 layers.

3M 8992 and generic green poly tape. This is the tape I've been using. It's great. Good enough tensile strength...some elongation to help it conform to rim channels. 190g for the roll.

Generic orange poly tape. This is no better than the green stuff. When I attempted to stretch/elongate the tape, it tore. Basically it has slightly worse elongation, but no better tensile strength. Avoid.

Generic rusty red poly tape. About the same as the green stuff, so just buy the green stuff.

3M 8896/8898. This is one of the more popular tapes and honestly it's pretty good. The strapping tapes have superior tensile strength, but don't conform as well as the poly tapes. Adheres to carbon rims poorly.

I have some Ideal 9148 polyester tape. Anyone tried that, or know if it is equivalent to one of the tapes mentioned above?

http://www.idealtape.com/productpage.ph ... &tape=9148

I might try it and see how it holds up.

I forgot to mention that I want to use this on alloy clincher rims with tubes and not tubeless

Looks like it has similar properties to 3M 8991 and generic transparent blue poly tape. It's pretty thin and not as strong as Kapton/polyamide tape (which is even thinner.) 2 wraps would probably still be fine for tubeless, and definitely should be fine for a tubed clincher setup. Worst case is you just add a 3rd layer.

On another note 3M 8898/8896 adhesive is downright terrible on carbon rims...How is this one of the more popular rim tapes? The last time I unwrapped old 8898 tape, when I got down to the first layer it pretty much just fell off the rim.

Ok thanks.

I bet PTFE tape would work well also. I work with some 3M 5480/5481 that is pretty strong stuff. Maybe the adhesion wouldn’t be strong enough though.

Yeah the adhesion seems low, but I think silicone adhesives are better rim tapes than the rubber resin found on Stan's/Tesa and 3M 8896/8898. The 5481 tape is particularly thick, one wrap would be as thick as two wraps of the green poly tape.
