Position bike in a repair stand or lean against wall. Ensure drivetrain can be back-pedaled and that
lower section of chain is horizontal with ground. This is most easily accomplished using a repair
stand. Alternatively, the Chain Pig will work in most gear combinations and different gear
combinations can be used to change chain angle.
Usage
1. Squeeze together the closure buttons to release the upper body and remove as shown.

2. Attach Chain Pig around lower section of chain and position hook around lower derailleur pulley axle

4. Pedal the drivetrain backwards 20-30 revolutions.

derailleurs. If you experience either issue, you can try removing the derailleur hook from the Chain Pig
and reinstalling the hook upside down.
For use on bike without derailleurs, like those with single-speed or internally geared drivetrains, we
suggest removing the derailleur hook and holding the Chain Pig in place during use with your free hand.
Replacement parts available. Visit pedros.com for details.
Clean your cogs, chainrings, and derailleur pulleys using a drivetrain brush, like Pedro’s Toothbrush.
Do not store fluid in your Chain Pig.
Please dispose of used cleaning fluid responsibly.
