Featuring a profile machined face, this clamp is structurally balanced putting the material and strength where needed. The ARC SCS uses 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.
