USE OF THE TORQUE STOP OF THE STEM TO THE FORK TUBE

The OC Mountain Performance and Mountain Control stems compatible with the Spinblock function have a stop in the area where the stem is attached to the fork's steerer tube to ensure that the recommended torque is not exceeded.

The torque stop is specific to each stem model, and is installed on the stem.

ASSEMBLY COMPOUNDS FOR HANDLEBARS

On carbon handlebars, apply a light coating of carbon rubbing compound to the handlebar-to-stem mounting surface.

For aluminium handlebars with aluminium stems, do not apply any mounting compound to the clamping area of the handlebar.

If you are going to use a carbon stem, whether the handlebar is aluminium or carbon, apply a light coating of carbon rubbing compound to the mounting surface of the handlebar to the stem.

If it is necessary to reinstall the torque stop on the stem, it is necessary to remove the bolts from the clamp area of the stem to the fork to install the torque stop and then reinstall the stem bolts.

The torque stop is not essential for the use of OC stems. If the torque stop is not installed, be sure to follow the stem bolt torque directions for each OC stem model.
