0.5mm Dissidence Headset Spacer - Premium Bicycle Headset Shim for Smooth Steering & Bike Maintenance - Perfect for MTB, Road Bikes & Cycling Repairs

This paper-thin washer is designed to go underneath your dust cover and remove any rubbing between it and the headtube. The 0.5mm size will give your setup a cleaner look, but we suggest purchasing a 2mm headset spacer along with this, just in case.
