I'll have to give them another try, since I have four left.

I bought them with flip bikes in mind, but I have enough wheel sets that maybe I can work them into the rotation somehow. I have a good tire jack, but like someone else who posted above, I dread the thought of having to deal with super-tight fitting tires should I get a flat in the middle of a long ride.
