1-1/8 Aluminum Mountain Bike Headset Top Cap & Spacer Cover

Upgrade your mountain bike cockpit with this precision machined top cap and spacer set. Designed specifically for 1-1/8 inch steerer tubes, it replaces worn factory covers that frequently strip or rust after regular trail riding. The AL6061-T6 aluminum body delivers excellent stiffness without adding unnecessary mass, while the included stainless steel bolts resist mud and moisture far better than standard hardware.

You will see an immediate difference in how clean and intentional your front end looks. Because the component weighs just 15.6 grams, your handling stays sharp and responsive on rough terrain. The design slots directly into standard headset stacks, allowing you to swap it out in minutes with a simple hex key.

Benefits & Tips

Clean the steerer tube threads before installation so the new bolts seat smoothly without catching. Pair the cap with matching stem spacers to create a unified cockpit aesthetic that reduces visual clutter. Inspect the fastener torque every few rides, especially after crossing puddles or taking the bike through a pressure wash.
