Expander/Spacer/End-Cap

Upgrade your cockpit with essential expander plugs, headset spacers, and handlebar end plugs. These small but critical components ensure your stem and handlebar assembly is secure, safe, and properly tuned. An expander plug (or compression plug) anchors the fork's steerer tube, while headset spacers allow for precise stack height adjustment. Quality end caps (or bar end plugs) protect your handlebars and are crucial for safety. For budget-conscious cyclists, durable aluminum expanders and composite plastic spacers offer a price-efficient solution without compromising on function. Finding affordable, reliable parts in this category is key to a safe and custom bike fit.
