Used on Ican Aero 40 rims with Conti 5000 on a Felt FR1. Used just a single layer rather than the double that was suggested. No need for double as near as I can tell and it was tough enough to get the tires on with the single layer. I wore out the tire, down to the casing, with no issues.
Near as I can tell, it's doing what it's supposed to. I do lose a tiny bit of air between rides, but nothing drastic, and I can't say that the rim tape is why. I'm using just a single wrap on my road bike and running Conti 5000 TL.
This is the best tubeless tape easy to apply and sits in the rim well, durable and flexible, 2 layers is plenty but 1 is sufficient, holds air. I've scrapped other tape jobs with inferior tape but I have never had to re-tape when I applied Stan's. Even when rim tape is supplied in my wheel order, I will only use Stan's.
nice alternative to cloth or thicker synthetic rim tape/strips, being thinner may help with mounting those really light tires like Kenda Kaliente on Mavic Open Pro rims. One thing that happened to the roll I got, as I applied the tape to the rim, there was a small cut on the end of the tape and it separated a thin strip on one edge from the main piece I was applying to the rim, after I applied a few feet, I notice the tape I was applying getting thinner at the rim and a ridge growing on one side of the roll where the sliver left there was growing in width, I had to start over after I wasted a few feet of the tape. Luckily, there was enough to finish both wheels.
