WHEELS Mfg Headset Spacer Kit

These spacers are designed specifically for standard 1-1/8 inch steerer tubes, which is the most common size for modern road, mountain, and hybrid bikes. If your bike uses a tapered or straight 1-1/8 inch steerer, these will fit perfectly.

The kit includes four spacers with thicknesses of 2.5mm, 5mm, 7.5mm, and 10mm. This variety allows you to fine-tune your handlebar height with precision.

These are constructed from durable alloy with an anodized black finish. They offer a more robust and premium feel compared to plastic alternatives, ensuring they won't crack or deform under pressure.

Yes, you can certainly swap out carbon spacers for these alloy ones. While alloy is slightly heavier than carbon, it is often more durable and less prone to cracking if your stem bolts are overtightened.

No special tools are required, but you will need a set of hex keys to loosen your stem bolts. You will need to remove the top cap and stem to slide these onto the steerer tube, then re-tighten everything to the manufacturer's torque specifications.
