Rejoining a Broken Chain With a Quick Link

A snapped chain is the classic way to end up walking, and a tiny quick link in your saddle bag turns it into a ten-minute stop. Use a chain tool to push out the damaged link close to the break, fit the quick link to join the two ends, then hold the rear brake and press down on a pedal to snap it shut. Quick links are made to suit particular chains, so carry the one that matches yours rather than a spare from another bike. Removing links leaves the chain shorter, so stay out of the extreme gears on the ride home or you risk bending the derailleur. At home, fit a correctly sized chain; a pair of quick-link pliers makes opening a stiff, grimy link far easier.
