My front teeth have become sensitive to pressure, making it painful to bite open the valve on the "standard" Specialized water bottles. I guess I could open the valve by hand before removing the bottle from the cage, but due to arthritis that isn't always easy for me either. (Yes, I'm a bit of a mess.
) Can anyone recommend a bottle, preferably with a capacity of around 24 ounces or 700 ml, with a valve that's easier to open?
