Park Tool’s GearClean Brush has a unique
design. A large comfortable handle with a
curved, toothed-end reaches dirt deep between
the gears, and tough nylon bristles clean the
derailleur and chain. Saves wear and tear on
your chain and freewheel. Works great on brakes
or other places where dirt collects. 11-speed
compatible. Handy size to take along for quick
cleaning anywhere. Made of sturdy nylon.
