The Problem Solvers Locking Headset Spacer is handy during headset servicing for keeping the fork in place when the top cap and stem are removed. It's also great for keeping the fork in the frame when you're shipping your bike in a box, which usually requires removing the stem and bars. This quality piece is for 1 1/8-inch forks and is CNC machined of light, durable 6061 aluminum and has a stainless-steel bolt.
