Product Description
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.
Park's Gear Clean Brush has a handle on one end with a curved, serrated edge perfect for cleaning between cassette cogs. The other end's tough nylon bristles are ideal for cleaning the derailleurs, chain and other drivetrain parts to keep them clean and prevent premature wear. It also works great on brakes and other components that collect dirt and grime.
