Headset adjustment eliminates handlebar wobble and ensures smooth steering. Loose or tight headsets compromise bike handling and safety.
Quick Answer: Loosen stem bolts, adjust top cap to remove play while allowing smooth rotation, then retighten stem bolts to secure. Check by lifting front wheel and turning bars—steering should move freely without notching or looseness.
Checking Headset Condition
Apply front brake and rock bike forward/backward. Clunking or movement at the headset indicates looseness. Lift the front wheel and rotate handlebars—notchy or stuck movement shows overtight adjustment or worn bearings.
Adjustment Procedure
Loosen stem bolts 2-3 turns. Turn the top cap bolt clockwise in quarter turns until play disappears. Test steering rotation—it should move smoothly without binding. Once correct, hold handlebars straight and tighten stem bolts to spec.
