Full Speed Ahead Headset Spacers

These spacers are designed for a standard 1-1/8 inch (28.6mm) steerer tube, which is the most common size found on modern road and mountain bikes. Please verify your fork's steerer diameter before purchasing to ensure compatibility.

Polycarbonate is significantly lighter than aluminum and completely immune to rust or corrosion. This makes them an excellent choice for riders who frequently ride in wet or muddy conditions and want to shed a few grams from their cockpit.

Each pack contains ten individual spacers. Since each spacer is 10mm tall, you have a total of 100mm of adjustment range available to dial in your handlebar height.

Yes, you can mix and match these with metal spacers without any performance issues. Just ensure that the total stack height does not exceed the maximum limit recommended by your fork manufacturer.

Absolutely. While they are lightweight, the polycarbonate construction is robust enough to handle the vibrations and impacts associated with standard mountain biking. They are a reliable, long-term solution for adjusting your cockpit geometry.
