Single Speed Converter PRO

Bicyklon Single Speed Reducer Pro – fast cassette-to-SS conversion

The Bicyklon Single Speed Reducer Pro is an easy and cost-effective solution for converting a geared drivetrain into a clean, reliable single speed setup — without replacing the hub. Simply remove the cassette and mount the reducer to achieve a simple, durable and maintenance-friendly configuration.

The kit fits 8-, 9- and 10-speed Shimano-type freehub bodies. The steel 13T sprocket with a 7 mm flange protects the freehub and delivers long-lasting performance under load. The set includes seven black-anodized aluminium spacers, allowing precise chainline adjustment. A lockring is also included for secure installation.

Perfect for riders building a single speed bike for dirt, street, pumptrack or a minimal, no-nonsense urban setup.
