Perfect for dirt track, road trips, and racing. You can add a camera mount to your motorcycle helmet using the included extension arm and adhesive mount. The adhesive mount is slightly concave to match the curvature of most motorcycle helmets. For best results, it is recommended to apply the adhesive mount to the top or side of the helmet. The extension arm, which can rotate 180°, allows for adjustment to a wide range of angles, such as forward view, rear view, and blind spots. Using the included handlebar camera mount clamp, you can mount the camera to most standard-sized motorcycle bars with a diameter of 17mm to 39mm (0.66 to 1.53 inches), utilizing small or large bar clamp spacers. ✼••┈┈••✼••┈┈••✼••┈┈••✼••┈┈••✼ ✿.•Instant purchase welcome・Midnight silent purchase OK•.✿ *First come, first served for only one item♬.*゜ *Welcome to bulk purchases, please feel free to comment ♥Free shipping! ・Please understand that items are stored at home and shipped in simple packaging. ・Please check the actual photos for the condition of the product♪ ※In order to sell at a slightly lower price, we may ship the item without the box due to shipping costs. ・We inspect the products before shipping, but if there are any defects, please contact us "before evaluation". ✼••┈┈••✼••┈┈••✼••┈┈••✼••┈┈••✼ MEKNIC 360° Rotating Claw Clamp Mount Cycling Riding 1/4 Screw + Aluminum Alloy Extension Rod for GoPro Smartphone Mount Action Camera Gripper Monitor Bicycle/Motorcycle Clip Mount Compatible with GoPro/Insta360/DJI/SJCAM/EKEN/DJI OSMO 20187714.4
