WHEELS Mfg Headset Spacers

No, these are specifically designed for a 1-inch steerer tube, which is typically found on older road bikes, vintage mountain bikes, or certain touring frames. Most modern bikes use a 1 1/8-inch or tapered steerer tube, so you should measure your fork's steerer tube diameter before purchasing.

Each individual spacer in the pack has a thickness of 2.5 mm. This allows for very fine-tuned adjustments to your handlebar height compared to thicker, standard-sized spacers.

Yes, these aluminum spacers are compatible with carbon fiber steerer tubes. Just ensure you follow your fork manufacturer's torque specifications for the stem bolts to avoid crushing the steerer.

No, this pack includes ten identical 2.5 mm spacers. They are designed for riders who need a consistent stack height or want to make very incremental adjustments to their cockpit setup.

These aluminum spacers are significantly more durable and rigid than plastic alternatives. They provide a more secure interface between your stem and headset, which helps maintain proper tension and prevents the stem from slipping over time.
