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
Do all bikes have a master link?
Not all bikes have master rivets. If your bike has a derailleur, it’s unlikely that your chain will have a master link. Bikes that typically do have chains with master links are BMX bikes and one- or three-speed town bikes with internal gears. If the width is 1/8 inch, your chain should have a master rivet.
