Industry Nine Headset Spacer Kit

These spacers are designed for standard 1-1/8 inch steerer tubes, which covers the vast majority of modern mountain and road bikes. As long as your fork uses a standard straight or tapered 1-1/8 inch steerer, these will fit perfectly.

The kit includes four spacers with thicknesses of 2.5mm, 5mm, 10mm, and 20mm. This range allows you to fine-tune your handlebar height in small increments or make larger adjustments as needed.

Yes, these aluminum spacers are safe to use with carbon fiber steerer tubes. Just ensure your stem is properly torqued and that you have the correct amount of steerer tube exposed above the stem to safely accommodate the top cap.

The entire four-piece kit weighs 36 grams. It is a negligible addition for most riders, especially considering the benefit of achieving a more comfortable and efficient riding position.

Industry Nine uses a high-quality anodizing process that is generally resistant to fading and wear. While extreme UV exposure over many years can slightly dull any anodized finish, these are built to maintain their color and durability through regular riding conditions.
