The center photo is the heart and soul of the Stem Cap System. Stem Caps patent pending CNC machined headset covers are made from 6061 aluminum and produced in Lockhart, Texas. Buy one to replace your current headset cap then purchase the Light On PTSD snap-on Stem Cap Covers to complete the Stem Caps System.

Please note the Light On PTSD caps will not fit on a stock bicycle stem cap. Please add a Stem Cap Base to your cart if you have not already purchased one. Once you have a Base Cap you can order as many cover caps as you desire, and change them out as you wish. It can be done in seconds. These work on most 1 1/8" steer tubes. If you have questions regarding compatibility with your bicycle, please email Jason at
