In a world of complex appearances, the Sculpted series presents a subtle, well designed option for the riders who prefer to keep it cool. 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.
