Shakiness indicates that the headset is adjusted too loose. The easiest way to check for this is to apply the front brake and push the handlebars back and forth, front to back. If you feel a "clunk" it usually means the headset is too loose. You can determine that the looseness is in the headset and not the brake by resting a finger across the gap between the races of the top or bottom headset assembly. If the bicycle is in the workstand with the front wheel off, you can just push and pull on the forkends. | Shakiness indicates that the headset is adjusted too loose.

=== | ===Schwergängigkeit=== | ||
Stiffness results when the headset is adjusted too tight. Check for this by lifting the front of the frame so that the front wheel comes off the ground. Normally, the wheel and handlebar will flop to one side or the other by their own weight when you do this. If the front wheel and handlebars are off the bicycle and you turn the fork, you may feel a light, smooth, even drag from bearing seals -- this is normal. Roughness or uneven drag indicate problems. | Stiffness results when the headset is adjusted too tight. Check for this by lifting the front of the frame so that the front wheel comes off the ground.

Sometimes you will find both of these faults at the same time. This indicates a more serious problem, not just an adjustment issue. You may find that the headset is loose when the fork is facing straight forward, but gets tight when you turn the handlebars to one side or the other, or that it simply can't be adjusted.

The headset may have been assembled from mismatched parts. It's OK to replace only the bottom or top parts of the headset as a unit, but the two bearing races at the top, and the two at the bottom must match, and the bearing balls and retainer (or cartridge) need to be the right size, or else all bets are off. | The headset may have been assembled from mismatched parts.

All of the other ball bearings on a bike spend their lives rotating round and round, but headsets spend most of their time pointing straight ahead. Sometimes you will see that the bearing balls have created a neat row of little dents in the bearing surface of the lower frame cup and/or the crown race. This creates the effect commonly known as "indexed steering" where the balls sort of "snap" into place, and the fork tends to stick in the straight-forward position. | All of the other ball bearings on a bike spend their lives rotating round and round, but headsets spend most of their time pointing straight ahead.
