How do you separate a bike chain without a tool?
If your chain has a master link, remove the link by twisting it off with a pair of needle nose pliers. Press the nubs through to the other side to fully remove the link. You may need to use a hammer or wrench to tap the link so that it pops out allowing the chain to separate.
Are chain Quick Links reusable?
The quick link is designed for use with 11-speed chains and is, according to Shimano, not reusable. Quick links are dead easy to install. Place the quick link into the chain gap, align and snap together – usually done by applying pressure through the cranks.
Are Quick Links universal?
Shimano, SRAM and KMC quick links are designed for single use. Once installed, if you open the link to remove and clean the chain, for example, you should install a brand new quick link. That’s because the act of locking these quick links removes material weakening them.
