These are used to hold water bottle cages on bikes without braze-ons. They work best with cages that have an elongated mounting area and only on non-oversized frame tubes. They will not work on cages with short mounting tabs, like Nitto cages, but you can use them with VO bottle cages, it's just not a perfect fit.<br /><br />What's Included:<br />Two Clamps<br />Two Nuts/Bolts
