Tilt Classic SCS ClampConstructed to improve clamp technology, this simple design is trusted and reliable. Custom bolts with a 6mm hex key drive and 50% larger threads provide more clamping power and help keep the compression tight and bars in place. Every clamp bolt from Tilt comes with pre applied anti seize to prevent them from seizing to the clamp. For added compatibility, the removable shim allows use with both size handlebars.
