Park Tool GSC 3 Drivetrain Cleaning Brush

This dual-sided brush is specifically designed for cleaning hard-to-reach areas of the bicycle drivetrain. The long, stiff bristles of the GSC-3 are narrow enough to reach between the gears of tightly-spaced modern cassettes, while the slim contoured end is capable of picking grit and grime out of tight spaces such as derailleur pulley wheels.

A dirty drivetrain causes poor shifting and unnecessary wear to expensive parts. The Chain and Drivetrain Cleaning Kit contains everything needed to quickly and easily clean the chain, freewheel cogs, and chainrings. CG-2.4 works on nearly any bike including multi-speed, single-speed, and e-bikes. Includes: CM-5.3 Cyclone Chain Scrubber, GSC-1 GearClean Brush, 8 oz. bottle of Bio ChainBrite.
