Description

Specifically designed for cleaning hard-to-reach areas of the bike drivetrain, the Park Tool GSC-3 Drivetrain brush is dual-sided for getting between gears and into the derailleur pulley wheels.

Key facts
  • Long, stiff bristles are narrow enough to reach between the gears of tightly-spaced modern cassettes
  • Slim contoured end is capable of picking grit and grime out of tight spaces, such as derailleur pulley wheels
