I’ve got a set of Kovees. The rim strip is definitely one of my favourite things about it. It is definitely difficult to impossible to remove a tyre in a normal fashion (I’d be screwed if I slashed a tyre on a trail) but it’s pretty easy with the right technique. I support the rim over a plastic bin, grasp the tyre on either side and progressively lean until the bead pops. Airing up is insanely easy because of the strip (I’m pretty sure I could use a hand pump). And it’s so nice never having to having to deal with old peeling tape after a few tyre changes.
