Mount any item that utilizes the "Go-Pro" style adapter (light, camera, gps, etc.) to your RevGrips Pro Series Stem with our universal accessory mount. This convenient mount places your Headlight or Camera directly in the center of your bike which is exactly where it should be. K-EDGE and a number of others make an adapter that will mount directly to our accessory mount. Each and every Pro Series RevGrips stem is built so the light/camera mount can easily be installed at any time. It’s quickly removable with only two screws keeping it where it needs to be. (Light is NOT included) Total Weight: 11g Not compatible with Race Series Stem.
