Tension screws help hold your shoe securely to the pedal. As you continue to ride the bike, the screws may loosen slightly, causing your shoes to fit less tightly into the pedal when clipping in.
If it becomes too easy to clip in, we recommend tightening the screw on the back of the pedal using the 3 millimeter Allen key included with your bike. This will ensure a tight connection. We do not recommend loosening the screw at any time.
