If the quick-release doesn't hold the stem snug in place, you will need to adjust it. Open the quick-release lever. Turn the adjustment nut clockwise one half turn while keeping the lever from turning. Close the lever. Repeat this procedure until the stem is held snug in place. If the quick-release is too snug to close, you will need to adjust it.
