This Sunday is the Austin LIVESTRONG race and my husband told me to go buy heavy-duty tubes and slime so he can get our tires ready. He doesn't want to ride on the highway and deal with flats. (He wanted to do this anyway, but now he has a special incentive.)
So, what's your opinion of both/either? Will I be able to tell any discernible difference when I'm riding my hybrid? Will it make it harder to ride? Do they work?
