How to Take Apart a Chain by the Master Link

For the novice bicycle repairman, breaking the chain away from the drivetrain for the first time can be a puzzling experience. To remove traditional bicycle chains, you need a chain breaker tool and a fair amount of patience. The advent of the master link greatly simplified the chain removal and re-installation process. Chains with master links are typically found on single-speed or fixed-gear bicycles, though newer derailleur bicycles may be equipped with master link chains.

Instructions

    • 1

      Turn your bike upside down so that it rests on its seat and handlebars. If you have a bicycle repair stand or carrying rack on the back of your car, you may hang it from either one of these instead.

      Loosen the rear quick release skewer or hub bolt to release tension on the wheel. If your rear wheel is attached with quick release skewers, simply flip up the lever and turn it counterclockwise until the wheel slides forward in the frame's dropouts. If your rear wheel is attached with a hub bolt, use a large adjustable wrench to loosen the bolts on each side of the wheel.

      Don your work gloves to protect your hands from the dirty grease on your bicycle chain. Inspect the entire length of your chain until you find the master link. It will contain an extra hole in its outer plate and look visibly different than the other links.

      Grasp the chain on either side of the master link and bend it outward, away from the drivetrain. Apply firm pressure until the rest of the chain separates from the master link.

      Pull the chain off of the rear and front cog and set it aside for cleaning or maintenance.
