Troubleshooting

Stem feels loose after installation

Ensure all steerer clamp bolts and bar clamp bolts are tightened to the correct torque specifications. Check for any debris on the steerer tube or handlebar clamp surfaces.

Creaking noise from the handlebar area

Apply a small amount of carbon paste (if using carbon handlebars) or assembly grease to the handlebar surface within the clamp area. Re-tighten bar clamp bolts to the correct torque. Ensure bolts are properly seated.
