Important: Retain the original front and rear wheel spacers when removing the factory wheels. These spacers are required when installing the new wheel set.
The original brake rotors, rear sprocket, wheel spacers and associated hardware must be transferred from the factory wheels. Alternatively, separate rotors and a sprocket can be fitted if you want to prepare the new wheels as a more complete second wheel set. Installation information
Professional installation is recommended. The factory wheel spacers must be reused, and correct spacer placement, brake rotor alignment, sprocket alignment, chain tension and tyre clearance must be confirmed before riding.
After installation, check that both wheels rotate freely without brake, chain or suspension interference. Spoke tension should be checked after the first ride and periodically as part of normal wheel maintenance. Important compatibility information

Owners of road-legal Ultra Bee models should confirm applicable compliance requirements before using this wheel set on public roads.
