CYCLUS TOOLS - Universal tool for installing the fork crown race. Suitable for diameters 1'', 1 1/8'', 1.5'' and 1.8''. Enables quick and precise installation of the crown race onto the fork.

Thanks to the integrated guide, it ensures precise centering on the fork steerer tube. Ideal for fork crown races with diameters 1'', 1 1/8'', 1.5'' and 1.8''.

Instructions for use: Use the driver to press the headset crown race onto the fork. First, select the appropriate adapter sleeve. Ensure that the adapter sleeves are correctly positioned in the driver to prevent the crown race from jamming. The adapters feature a chamfer on one side of the hole, allowing the installation of a crown race with a sealing lip without damaging it.

The guide integrated into the driver sleeve ensures precise centering on the fork steerer tube, preventing the crown race from jamming. The driver should not be used as a hammer: for installation, use a suitable hammer. Before proceeding, lightly lubricate the crown race seat with bearing grease.

Maximum allowed fork steerer tube lengths:

• 1'' = 340 mm


• 1 1/8'' = 335 mm


• 1.5'' = 315 mm

The upper diameter of the fork steerer tube determines the maximum allowed length.
