Adjusting the handlebars

Removing/mounting the stem

Caution! The stem fixes the steering head bearing and holds the front fork with the wheel.After the stem has been removed these parts are no longer supported and may fall down off the frame. Hold the fork with one hand or secure the fork e.g. with a cable tie at the frame.

Remove the lower quick release of the seat mount and lift the seat.

Take off the cap of the steerer tube and remove the hex-headed screw in the cap complete- ly.

Undo both clamping screws at the side of the stem. Now you can remove the stem upwards.

To mount the stem put it on the lubricated steerer tube.Tighten the clamping screws at the side a little bit, put on the cap and tighten the hex-headed screw again through the cap. Adjust the steering head bearing. (see below).

Then tighten the two clamping screws alternately with 8-10 Nm. Check the clamping by trying to turn the stem against the front wheel.

Adjusting the head set bearing play

The head set bearing has to be adjusted so that the fork with the front wheel turns easily without showing play.

To check the bearing play pull the front brake and grab with your other hand the upper bearing cup. Now move your bicycle back and forth. If the steering head bearing has play the upper cup moves noticeably in contrast to the fixed part. In that case undo the clamping screws and tighten the screw in the cap a bit more.

To check whether the front wheel turns smoothly lift your bicycle at the frame so that the front wheel moves freely above the ground. Lean your bike to the side. Now the handlebars should moove smoothly immedia- tely.When you hold the frame straight and push the handlebars slightly they should move smoothly from their middle position. If the bearing is too tight undo the clamping screws at the side and loosen the hex-headed screw in the cap a little bit by turning it anti clockwise. Now move the stem upwards by swinging it a little bit.

After you have adjusted the bearing play check if the stem is adjusted in a parallel position to the front wheel and tighten the two clamping screws alternately with 8-10 Nm. Check the clamping by trying to turn the stem against the front wheel.

Check whether the handlebars move freely without touching the frame or the seat.
