Buying advice

When buying bike headset spacers, consider the material (aluminum is durable and affordable, carbon saves weight but costs more), size range needed for your stem height adjustment, and color matching. Ensure the spacer inner diameter matches your fork steerer tube (usually 1 1/8 inch). For most riders, an aluminum kit with multiple thin spacers offers the best value and flexibility.
