I needed tape for a couple of wheelsets that I built using Velocity A23 rims - these 23mm rims need 21mm tape. I am not running tubeless, so do not need the time-consuming adhesive tapes. The Zipp tape was very easy to install and is, as it says, ultra thin which makes tire installation easy. So far, no issues with durability.
When I received these in the mail, I was somewhat skeptical if the 700x18mm rim strips were going to fit on the wheels of my 1980's Takara Sport 10 touring bike. But, with some effort, they fit like a glove. I bought these so that I could replace the 30 year old rubber rim strips, because I have bought two 27x1-18 Continental SuperSport road tires from this website that have to be aired up to 102 psi since I am a heavy rider. But I'll have to wait until it's springtimesummertime.
