The Canopus Speed Star Bearing is an inexpensive way to improve the action of your bass drum pedal. This ingenious little product is an add-on bearing/rocker hub that goes between the spring assembly and the pedal. The Speed Star Bearing reduces friction while increasing the smoothness of your pedal's action. Before bailing on your old, reliable bass drum pedal, breathe new life into it with the Canopus Speed Star Bearing. A very affordable upgrade that improves the ease with which you play. This particular model will fit DW5000 since 2000 (DW3000, DW6000, DW7000 and DW8000 with common hubs).
