The Pedro’s Chain Keeper is a small but indispensable tool for any bike mechanic, designed to hold your rear derailleur and chain in place when the rear wheel is removed. Whether you’re transporting your bike, performing drivetrain maintenance, or cleaning and degreasing your components, this simple device keeps the chain secure and prevents it from flopping around or damaging your frame. Its thoughtful design makes wheel removal and reinstallation easier, tidier, and more efficient.

Constructed from durable polymer, the Chain Keeper offers strength and reliable performance without adding unnecessary weight. Its hooked shape accepts most quick-release or thru-axle derailleur hangers and aligns the rear derailleur and chain in a natural position. This ensures the chain stays tensioned and the derailleur doesn’t shift out of place, protecting delicate pulleys and hanger threads while you work. The compact size makes it easy to store in your home workshop or saddlebag.

The Pedro’s Chain Keeper is especially useful when you’re cleaning the drivetrain, swapping tires, or servicing brakes and hubs. By keeping the chain and derailleur stable, it saves time and frustration so you can focus on the task at hand. Reliable, affordable, and easy to use, this tool is a smart addition to any cyclist’s toolkit.
