Full Speed Ahead Headset Spacers

These spacers are designed for the industry-standard 1-1/8 inch steerer tube diameter. They are compatible with the vast majority of modern road, mountain, and hybrid bikes, but you should confirm your fork's steerer size before purchasing.

Each spacer in this pack measures 5 mm in height. This allows you to make precise, incremental adjustments to your handlebar height by stacking them as needed.

These are constructed from high-quality aluminum. This material choice provides a durable, rigid connection that won't compress or deform over time like some plastic alternatives.

Each pack contains 10 individual 5 mm spacers. This quantity is typically sufficient for most bike builds or for making multiple adjustments across different setups.

No special tools are required to install the spacers themselves. You will only need the appropriate hex key to loosen and tighten your stem bolts when adjusting your headset assembly.
