I read other reviews saying these grip too tightly, but I say just tight enough. They are definitely on the firm side, but they entry and exit is smooth, so the firmness is great. Very little chance of them ever coming out, and no sloppyness.
Needed 2 new bottle holders to go with my new cannondale and these just went perfect with it. I been on a few rides and the waterbottles do not move from them at all. Cant go wrong with the price....cheapest i seen these for anywhere. Fast shipping as well will order from this sight again!
