Headset wrenches come in a variety of sizes to fit different types of headsets. To choose the right size wrench for your bike, you will need to know the size of your headset nuts and locknuts.

Once you have adjusted the headset to your liking, tighten the locknut back down to secure the adjustment in place. Be sure to check the headset for any play or wobbling before riding to ensure that it is properly adjusted.
