Bicycle Headset Top Caps

Secure your front-end assembly, protect steerer bearings from water and grit, and add custom style to your cockpit with our Bicycle Headset Top Caps collection. Placed atop the stem or upper headset spacer, the top cap works in tandem with the M6 preload bolt to pull the fork steerer up and eliminate bearing play before the stem bolts are torqued down. Choose from lightweight CNC-machined 6061 aluminum top caps featuring laser-etched graphics and vibrant anodized colors to complement custom frame accents, high-modulus carbon fiber top caps engineered for ultralight road and gravel race builds, or integrated multi-tool top caps designed to conceal hidden chain tools and bit drivers directly inside the steerer tube for trailside repairs. Manufactured with countersunk bolt seats and weather-resistant seals, these top caps deliver dependable performance.
