Park Tool GSC-3 Drivetrain Cleaning Brush

The Park Tool GSC-3 Drivetrain Cleaning Brush was especially designed for cleaning hard-to-reach areas of the bicycle drivetrain. The long, stiff bristles of the GSC-3 bike cleaning brush are narrow enough to get between the gears of modern cassettes with tight spacing. With the slim contoured end of the brush, dirt and grime can be removed from tight areas, such as the front derailleur.
