Frame Preparation
Check frame and fork dropouts to ensure that they are parallel to each other. Use an
appropriate tool made by a reputable bicycle tool manufacturer. Non-parallel dropouts
may damage or compromise the performance of your hub.
Installation and Removal of the rotor
Please follow your brake manufacturer’s specifications for rotor installation and rotor
