The heart and soul of the Stem Cap System. Our patent pending CNC machined headset covers are made from 6061 aluminum and produced right here in Lockhart, Texas. Designed to work on both 1 1/8" mountain and road bikes, the new shallow depth is compatible with traditional alloy steerers tubes as well as carbon forks.

Buy one to replace your current headset cap then purchase any of our snap-on Stem Cap Covers to complete the Stem Caps System.

These work on most 1 1/8" steer tubes If you have questions regarding compatibility with your bicycle, please email us at jason@stemcaps.com
