Designed specifically for holding oversized bars. This clamp has a structurally balanced machined face that puts the material strength exactly where needed. Custom bolts with a 6mm hex key drive and 50% larger threads provide more clamping power and help keep the bars in place and compression tight. Every clamp bolt from Tilt comes with pre-applied anti-seize to prevent the bolts from seizing to the clamp. This clamp does not come with a shim but will work with standard bars with a shim. Compatable with Oversized and Standard Size bars. Shim NOT Included. Shim must be purchased seperately for running standard bars!
