Bicycle Headset Spacers

About

Customize your handlebar height and set accurate front-end bearing tension with our Bicycle Headset Spacers collection. Placed on the fork steerer tube between the headset top cap and stem face, these simple yet critical components allow riders to fine-tune cockpit stack height for optimal posture and comfort. Choose from ultra-lightweight 3K and UD carbon fiber spacers designed for high-performance road and gravel race builds, precision-machined 6061 aluminum spacers featuring laser-etched logos and anodized color options to match custom cockpit accent themes, aerodynamic tear-drop shaped spacers engineered specifically for integrated cable-routing cockpits, or interlocking spacer kits that lock together to prevent rotation and rattling on aggressive off-road trail descents. Available in standard steerer diameters and varied height increments (2mm to 20mm), these spacers deliver precise front-end adjustment.
