Bike quick release skewer keeps loosening

A quick release that won't stay tight is usually not closed with enough force, or the skewer's internal cam or spring is worn.

Symptoms

  • Wheel feels loose or shifts slightly in the dropouts
  • Skewer lever doesn't feel firm when closed
  • Wheel has come loose while riding
  • Lever position ends up loose after a bump

Likely causes

  • CommonSkewer not closed with enough forceA quick release needs firm hand pressure to close properly, not just a light flip.
  • CommonIncorrect adjustment of the tensioning nutThe nut on the opposite side from the lever sets how much force the cam applies and needs periodic adjustment.
  • PossibleWorn or weak internal spring or camSkewers can wear out over years of opening and closing.

What to do

  1. Open the skewer fully and check the small springs on each side are present and in good condition.
  2. Close the skewer with the wheel properly seated in the dropouts, adjusting the tensioning nut on the non-lever side until the lever requires firm hand pressure to close about halfway through its arc.
  3. The closed lever should leave an imprint in your palm and require real effort to close, not flip shut easily.
  4. Check that the lever, when closed, doesn't stick out past the fork or frame where it could catch on something.
  5. Test wheel security by trying to move the wheel side to side and up and down in the dropouts once closed.
  6. If it still won't hold, inspect the skewer for a worn cam or bent shaft and replace it if damaged.
  7. If you're unsure about correct skewer technique, a bike shop can demonstrate the proper closing force and check the skewer's condition.
