Make sure you purchase a headset that matches your steerer tube inside diameter and your steerer diameter.
Thnaks. Do you mean the head tube.? the tube connected to the fork is 1" but there was a shim when I took it apart. So does that mean a 1" 1/8 headset should have been used.
Is "steerer tube" the head tube?
