Introduction

The headset on a bike is the most important bearing on the bike. It allows you to balance the forces while you're riding so you don't fall over. If it's too loose or too tight the bike may be uncomfortable to ride and the headset will wear out faster than if it's correctly adjusted

<h3>Step 1</h3><p>Grab the rear section of the bike – the part connected to the back wheel – at the front of the top tube. Lift the front wheel off the ground. Turn the bars. They should rotate smoothly left to right with no clicks or sticking points. The most likely problem is the front wheel tending to rest at the straighter head point.

Loose Enough?

Grab the rear section of the bike – the part connected to the back wheel – at the front of the top tube. Lift the front wheel off the ground. Turn the bars. They should rotate smoothly left to right with no clicks or sticking points. The most likely problem is the front wheel tending to rest at the straighter head point.

Pro Tip

Watch out for interference from any control cables. It may give a false negative.

Detecting play in the headset on a bike

You can detect tiny amounts of play in a headset on a bike by placing your finger at the point where the top tube meets the forks when make your check.

Pro Tip

Checks during adjustment of a threadless steerer headset are made while the handlebars are unlocked. Do the ‘too tight’ test by turning the wheel, and the ‘too loose’ test using the method described below.

Pro Tip

If the bike has no front brake or telescopic forks turn the front wheel perpendicular to the back wheel and push the bike forward to detect any play in a headset on a bike.
