The new XP Quick Release Cycle Light Clamp is a Quick Release Mount that is able to rotate in the direction as required by the cyclist. It is a bolt on replacement for the O-ring mount. All you need to do is remove the foot piece from the existing light and attach the XP Quick release mount. The bottom part clamps to any size handlebar with 2 different thickness shims for a snug fitting installation.
The top part is compatible with all of our Extreme Cycle Lights with the exception of the original XP3. On some of the lights, the XP-QR clamp does not sit very elegantly. Take a look at the pictures showing various lights with the XP-QR mount. If your XP3 Cycle did not include the XP-Quick release mount it is not compatible.
