When To Replace The Headset

Bearings on a bicycle allow the parts to rotate relative to one another. The headset allows the fork to turn smoothly while riding. Bicycles, and all two wheeled vehicles, make small self-corrections in steering while travelling forward. If the headset is pitted or worn, these corrections are not made smoothly and steering/handling suffers. Very worn headsets tend to "lock up" when the front wheel is pointing straight. Your headset should be replaced as soon as this problem occurs to prevent personal injury or expensive, unwanted damage to your bike in the event of a crash. You will need this Park Tool CRS-1 Headset Crown Race Setting System to do the job properly.

NOTE: For oversized column length in 1-1/4" or 1-1/2" use the Park Tool CRS-15.2 Crown Race Setter.
