Speedline Parts | UltraLight PolyCarbonite 1 1/8" Headset Spacers

The Speedline Polycarbonite Spacers are lighter than Aluminum AND Carbon Fiber. They also offer a trick look to any ride with their translucent appearance.

How light you ask? On a Park Tools Digital scale, one spacer won't even register! Throw on the full set of 3 and it registers 4 grams. That's crazy light!

Available in a 3-Pack:

- 2X 5mm

- 1X 10mm

This kit includes a total of 1/2" Spacer Stack.

You may need 2 or more packs depending upon the length of your fork's steertube.

Available in Clear Red, Clear Blue, White and Crystal Clear.
