This is a Rec-Mount for clamping action cameras like a GoPro to the handlebars of bicycles and motorcycles. Even without a device attached, the mount itself is small, so you can ride without it being noticeable. Even when a camera is attached, fixing it to the bottom at the base of the handlebars is a good point, as it doesn't give the impression that you're "filming." Features: Material: AL6061 Aluminum CNC machined product Made of aluminum, not plastic, so it has a high-quality feel. It hardly deteriorates even when exposed to rain and wind, and can be used for a long time. Compatible models: Compatible with GoPro HERO series Examples: HERO3 / HERO3+ / HERO4 / HERO5 / HERO6 / Hero7 / Hero8 / HERO9 / Session / Black / Black Edition, Silver Edition; mounting is possible if the old model mounts fit, regardless of the new model.
