How Does a Chain Go on a Mountain Bike: A Step-by-Step Guide
A chain on a mountain bike is connected to the front chainring, or sprocket, and the rear cassette, or group of gears. The chain is placed onto the teeth of the chainring and cassette and is then tightened by releasing the rear derailleur and pulling the chain tight before re-engaging the derailleur. The chain is then tested to make sure it shifts smoothly between gears and is properly lubricated for optimal performance.
