Product Information

Full details

For cyclists seeking to shave grams off their bike, M Part Splined Alloy Headset Spacers offer a lightweight solution for headset adjustment. The key benefit is their significantly reduced weight compared to standard alloy spacers, achieved through a splined internal construction for added rigidity. A potential caveat is that their specialized design might be overkill for casual riders prioritizing durability over minimal weight.

Are these spacers compatible with all bikes?

They are compatible with bicycles featuring a 1-inch (25.4 mm) threadless steerer tube.

The splined internal construction provides additional rigidity and strength to the spacer without adding weight.

Troubleshooting

Spacer does not fit steerer tube

Ensure you are using a 1-inch (25.4 mm) steerer tube. These spacers are not compatible with 1 1/8" or other oversized steerer tubes.

Spacer appears loose after installation

Verify that the stem bolts and headset top cap are correctly tightened according to your bicycle manufacturer's torque specifications. Ensure no debris is present between the spacer and the steerer tube or stem.

Anodized finish is damaged

Avoid using harsh chemicals for cleaning. If minor scratching occurs, it is cosmetic and does not affect performance. For significant damage, consider replacement.

Setup, Compatibility & Care

Setup:

M Part Splined Alloy Headset Spacers are designed to fit standard 1-inch (25.4 mm) threadless steer tubes. Installation involves sliding the desired spacer(s) onto the steerer tube above or below the stem before tightening the stem bolts and top cap.

Compatibility:

  • Steerer Tube Diameter: Compatible with 1-inch (25.4 mm) threadless steerer tubes.
  • Headset Type: Suitable for standard threadless headsets.

Care:

Clean the spacers with a soft, damp cloth. Avoid abrasive cleaners or solvents, as these can damage the anodized finish. Periodically check for damage or wear, especially if riding in harsh conditions.
