I’m typically using Stans rim tape now. I think it is kapton with some white tint mixed in, kapton is typically clear/yellowish. I know two layers are recommended but I only lay down one. I have a lot of trust in the durability of the material. Has anyone ever had issues wit one layer of Kapton or Stans failing?
FSA makes a non-adhesive continuous strip (like the Conti) that is thin and stretches slightly into place. I like this one if it can closely match the channel width of the rim I’m using. It’s handy if you think you may need to remove it for access to nipples, etc.
I’ve tried the Conti black strips too, seem to recall them being thicker. They might be fine.
I’ve given up on the cotton Velox in favor of plastic as it dries out faster when wet.
