The ORBEA STEM TOPCAP ST-MP10/21 HS02-30 is a precision-engineered top cap designed to finish off your cockpit with a clean, secure, and reliable interface at the top of your headset. Mounted on the stem and compressing the headset assembly, this top cap helps keep your steering smooth and your headset properly preloaded. It is ideal as a replacement for a worn or damaged cap, or as a fresh finishing touch when you are updating your stem or rebuilding the front end of your bike.
Built to match ORBEA’s quality standards, this stem top cap is compatible with common modern threadless headset systems that use a star nut or compression plug. Installation is straightforward: simply place it on top of the stem, insert the bolt into your existing star nut or plug, and tighten to the recommended torque to set bearing preload before tightening the stem bolts. Whether you ride road, MTB, gravel, or urban bikes, a solid and well-fitted top cap is essential for precise steering, reduced play, and long-term headset performance.
