Our Accessory Bar is 22.2mm for compatibility with many accessories - but sometimes lights/GPS/phone mounts only come in 31.8mm or 35mm diameters. Use these 3d printed shims to mount any accessories that need a wider clamp diameter.
The shim is designed to slide onto the end of the bar (not flex over it). They can be installed onto the center of the accessory bar by sliding off one of the aluminum clamps, adding the shim, and reinstalling the clamp.
One 31.8mm shim is already included with every Accessory Bar, as of June 2025.
