The Flycam Swivel for Flexi Rig Stabilization System from Proaim is an extra tube that is connected to your gimbal rig handlebars through a set of bearings, enabling you to pan the camera freely with no obstructions. Perfect for lower-angle and backward-facing shots, the Swivel works with 30mm handlebar tubes for the DJI Ronin and with 25mm tubes for the DJI Ronin-M using the included shims.
