I bought some new bontrager tubeless tires and they are extremely difficult to first install. I broke a couple of tire levers trying different methods then took it to my LBS and they said it was a 2 person job. They said they would get easire after riding them and breaking in but I fear changing a flat anytime soon. I will look into something different next time since i won't ride them tubeless. I was told the bontrager tubless rims are not that good for running tubeless than some other tubeless designs out there.
