Acros “The Clamp” manual

Check for bearing play:

Wrap your fingers around the upper bearing case and the upper part of the fork. Pull the front brake lever and move the bike back and forth.

Stem adjustment:

Loosen the stem bolts and the torx screw of The Clamp headset.

This manual describes the adjustment of Acros headsets with “The Clamp” system to set the bearing play. Required tools:

- Acros torx tool “The Clamp” (alternative torx TX6 wrench)

- Allen key fitting for the stem bolts (if possible use a torque wrench)

Press the stem down against the fork and align it straight to the front wheel.

Tighten the stem bolts with the required torque.

Reducing the bearing play:

Slowly tighten the torx screw until you feel a light resistance.

As the Torx screw in turned clockwise the indexing marks on the top and bottom of the upper cap will move together, reducing bearing play. Do not over tighten Torx screw as this can cause potential damage to bearing and headset components. The headset should not have any resistance and should rotate easily when the handlebars are rotated from left to right. If bearing play is detected, confirm correct assembly of all components and repeat stem and headset adjustment.
