The SIMWORKS With Me Brass Tapered Spacer is designed to match the outer diameter of the chromoly and aluminum With Me Spacers, allowing for a smoother transition from headset to stem. The wide and thick bottom shape fits snugly with headset part's wide top surface, creating a beautiful line. The precise cutting and sharp edge finish highlight the skill of Japanese small factories. Brass is a material that changes appearance little by little each time it comes into contact with the air or the warmth of your hands, from its initial bright golden color to a deep antique color. Small scratches and tarnish are part of the process of brass maturation. The longer you use it, the more it will fit your hand and the color will settle. This change over time is one of the charms of brass as a material.
