Learn how to install your Stix Headset Spacer Mount for a clean, integrated bike light setup. Step-by-step guide with common mistakes to avoid.
Quick Answer
Installing a Stix Headset Spacer Mount is a straightforward job that gives your bike a clean, integrated light setup. You'll replace one of your existing headset spacers with the included aluminum spacer and plastic mount.
What You'll Need
Before starting, ensure you have the Stix Headset Spacer Mount kit, which includes the aluminum spacer and plastic mount. You'll also need a set of Allen keys (typically 4mm or 5mm) to loosen your stem bolts and headset top cap. A torque wrench is recommended to tighten bolts to manufacturer specifications.
The mount is designed to work with standard 1-1/8" headsets. It positions the Stix headlight just under the stem in front of the head tube for a super-clean, integrated look. If your bike has a carbon steerer or a non-standard headset, check compatibility before proceeding.
Installation Steps
- Remove the Stem and Top Cap: Loosen the two stem bolts that clamp the stem to the steerer tube. Then remove the top cap bolt and top cap. Carefully lift the stem off the steerer tube, keeping the spacers in order. Common mistake: Not loosening the stem bolts before the top cap bolt can damage the headset bearings.
- Replace a Spacer with the Mount: Remove one headset spacer that matches the height of the aluminum spacer included with the kit. Slide the aluminum spacer onto the steerer tube, then place the plastic mount onto the spacer, aligning the interlocking system. Checkpoint: Ensure the plastic mount is oriented so the Stix light points forward. The interlocking tabs should click into place.
- Reinstall the Stem and Tighten: Place the stem back onto the steerer tube, followed by the top cap and bolt. Tighten the top cap bolt to remove play from the headset (do not overtighten). Then tighten the stem bolts to the manufacturer's torque specification. Common mistake: Overtightening the top cap can bind the headset bearings. Use a torque wrench if available.
- Attach the Stix Light: Slide the Stix headlight onto the plastic mount until it clicks into place. Test that the light is secure and aligned with your riding direction. Checkpoint: The Stix should be firmly attached with no wobble. If it feels loose, remove and re-seat it, ensuring the mount tabs are fully engaged.
