Do I need spacers on my headset?

How tight should headset spacers be?

With the front tire off the ground check to be sure that the wheel flops from side to side without your hands on the handlebar. A headset that’s too tight will hold the bike’s steering in place or slow it down as it flops back and forth. 2.
