Road cyclists and mountain bikers have relied on aftermarket solutions for quickly fixing their Shimano 11-speed chains for years, as Shimano never officially released a quick link for making repairs without the use of tools. However, all of that has changed with the introduction of the Shimano Quick Link For 11-Speed Chain, which allows you to quickly fix a broken chain without carrying heavy tools on the road and trail. To fix your broken chain, simply join the broken chain ends by snapping the quick link together in the intended direction (there's an arrow direction indicator) and applying a bit of pressure from a turn of the cranks. Voila! You're now ready to get back in the saddle on the road or trail. Please note, Shimano doesn't recommend reusing their Quick Links. Each package contains two quick links (that's four separate halves), so you can keep a spare handy after you've made a road or trailside repair to your chain.
