How do you disassemble 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.
If you don’t have this tool, then there are two hacks. First is to use a combination grip or needle nose plier, place the jaws of the tool on opposing diagonal edges of the quick link and squeeze. This method will likely damage the quick link and so replacement is strongly recommended.
The quick link is designed for use with 11-speed chains and is, according to Shimano, not reusable. Place the quick link into the chain gap, align and snap together – usually done by applying pressure through the cranks.
How often should I change my bike chain?
The 2,000-Mile Rule. To avoid this accelerated wear of your cassette and chainrings, a general rule of thumb is to replace your bike’s chain every 2,000 miles. Mind you, this is just a starting point. No two chains will wear at exactly the same rate because no two riders treat their chains the same. 4
What size chain is on a bicycle?
All modern bicycle chains are made to the “one-half inch pitch” standard, meaning from rivet to rivet is nominally 0.5 inches. The sprocket teeth are cut for this same one-half inch standard to accept bicycle chains. However, this does not mean all makes and models of chains are interchangeable.
