Park Tool’s patented 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. 10 speed compatible. Handy size to take along for quick cleaning anywhere. Made of sturdy nylon.

These pins fit Park Tool CT-5 Chain Tool. Made from hardened alloy tool steel. NOTE: Use a thread locker when installing the CTP, such as Loctite #242. Occasionally re-tighten the CTP in the handle.

The Cyclone Chain Scrubber brushes are replaceable. The RBS-5 brush set includes the large side scrubbing brush, two roller brushes, and two wicking foam blocks.

A worn chain shifts poorly and wears sprockets at an accelerated rate. The CC-3 is a "go, no go" gauge designed to accurately indicate when a chain reaches .75% and 1% wear, the points at which most chain manufacturers suggest replacement. Made from precision, laser cut steel. Fits derailleur and one speed chains including 9 and 10 speed.

This small chain tool goes anywhere and actually performs like a shop quality tool. The fine thread, special “V�- shaped handle, and super strong replaceable pin make chain removal and installation a breeze. The CT-5 works on any derailleur chain and has a “shelf� for loosening tight links. At only 77 grams, it’s the perfect take-along chain tool. 10-speed chain compatible.

NOTE: The CT-5 now uses the CTP replacement pin.

The CM-5 Cyclone Chain Scrubber uses an extra large solvent reservoir and a series of rotating brushes to get chains really clean. A magnet at the bottom of the Cyclone’s solvent reservoir draws particles scrubbed from the chain, effectively keeping them from being redistributed on the chain during cleaning. Durable sponge material draws solvent from the chain as it exits the Cyclone, reducing drips and mess. To make it easy to control and use, we’ve even added a handle. Works with all multi-speed bikes and some single-speed models.
