WAHL BROS. RACING No-Slip Drive Sprocket - 9-Tooth 02-579A

If you're running a full windowed track and want to maximize drive efficiency, the WAHL BROS. Racing No-Slip Drive Sprocket eliminates the rotating mass that slows acceleration and reduces lap times. By engaging four track lugs and clips simultaneously, this sprocket delivers consistent power transfer without the drag of unnecessary involutes—giving you the mechanical advantage serious racers demand.

This is a bolt-on upgrade for dedicated competitors who've dialed in their setups and know exactly what their frame geometry requires.
