Checking the headset backlash
 To check the handlebar headset backlash, close 
the quick release lever on the stem. Place the 
fingers of one hand on the upper headset cup, pull 
the front wheel brake with the other hand and try to 
push the bicycle backwards and forwards. 
 The headset cup halves must not move towards 
one another while you are doing this. Note that 
there may be noticeable backlash due to worn-out 
bearing bushes or brake lining backlash in 
suspension forks and disc brakes.
 If there is headset backlash in the steering headset, 
you must adjust it as soon as possible; otherwise, 
the headset will become damaged. You must make 
the adjustment as described in the stem manual.
